Homework

bull STUDY FOR VOCAB QUIZ

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

bull Along with the study of the geologic time scale the changes in life forms additions and extinctions are often accompanied by changes in environmental conditions on Earth These environmental changes have been influenced by the impact of an asteroid or comet climatic changes and volcanic activity

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

bull What information in the geologic record might lead scientists to infer that shallow seas covered much of the Earth during the Paleozoic Era

Cenozoic Era ndash Recent Lifebull Began about 65 million years ago and continues

todayndash Climate was warm and mildndash Marine animals such as whales and dolphins evolved

bull Mammals began to increase and evolve adaptations that allowed them to live in many different environments ndash land air and the seandash Grasses increased and provided a food source for grazing

animals

bull Many mountain ranges formed during the Cenozoic Erandash Alps in Europe and Himalayas in India Rocky Mountains in

the USA

Cenozoic Erabull Growth of these mountains may have helped to

cool down the climatendash Ice Ages occurred late in the Cenozoic Era

(Quaternary Period)

bull As the climate changed the animals had to adapt to the rise and fall of the oceans caused by melting glaciers

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

bull Essential Question What things first appeared in the Precambrian Time and became dominant during the Paleozoic Era

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Falcon Focus

bull What caused the mass extinction during Precambrian Time

bull Essential Question What things first appeared in the Precambrian Time and became dominant during the Paleozoic Era

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Mesozoic Era

bull Dinosaurs were also very active in this erandash First small dinosaurs appeared in the Triassic

Periodndash Larger and more abundant dinosaurs

appeared in the Jurassic Period

bull Small mammals and birds also appeared during this erandash The mammals were small warm-blooded

animals Hair covering their bodiesbull These characteristics help them survive in

changing environments

Mesozoic Era

bull The main plant life of this time were Gymnosperms or plants that produce seeds but no flowers ndash Pine Trees

bull Angiosperms are Flowering plants that during the END of this era

Mesozoic Era

bull This era ended with a mass extinction event about 65 million years agondash Many groups of animals including the dinosaurs

disappeared suddenly at this time

bull Many scientists believe that this event was caused by a comet or asteroid colliding with the Earth

Mesozoic Era ndash Mass Extinction Event

bull Asteroid or Comet collides with Earth

ndash Huge cloud of smoke and dust fills the airndash Blocks out sunlightndash Plants diendash Animals that eat plants diendash Animals that eat plant-eaters die

bull However not all forms of life died during this event Many animals that you see today are descendants from the survivors of this extinction event

Dinosaurs

Mesozoic Reptiles

Mesozoic Mammals

Mesozoic Plants

Flowering plants evolved towards the end of the Mesozoic Era

bull ABC brainstorming

Falcon Focus

bull What does the law of superposition states

bull Essential Question

bull What information in the geologic record might lead scientists to infer that shallow seas covered much of the Earth during the Paleozoic Era

Cenozoic Era ndash Recent Lifebull Began about 65 million years ago and continues

todayndash Climate was warm and mildndash Marine animals such as whales and dolphins evolved

bull Mammals began to increase and evolve adaptations that allowed them to live in many different environments ndash land air and the seandash Grasses increased and provided a food source for grazing

animals

bull Many mountain ranges formed during the Cenozoic Erandash Alps in Europe and Himalayas in India Rocky Mountains in

the USA

Cenozoic Erabull Growth of these mountains may have helped to

cool down the climatendash Ice Ages occurred late in the Cenozoic Era

(Quaternary Period)

bull As the climate changed the animals had to adapt to the rise and fall of the oceans caused by melting glaciers

bull This era is sometimes called the ldquoAge of Mammalsrdquo

Cenozoic Erabull Marine animal examples

ndash Algae Mollusks Fish and Mammals

bull Land animal examplesndash Bats Cats Dogs Cattle and Humansndash Humans are thought to have appeared around 35

million years ago (during the most recent period ndash Quaternary)

bull Flowering plants were now the most common plant life

Cenozoic Mammals

Flowering Plants were common during the Cenozoic Era

Falcon Focus

bull Which two eras of Earths history ended with major extinctions of species due to a catastrophic event such as an asteroid or comet

bull bull A Precambrian and Paleozoicbull B Paleozoic and Mesozoic bull C Paleozoic and Cenozoicbull D Mesozoic and Cenozoic

Essential Question

bull How would you explain how the Earths history has been influenced by climatic changes

Falcon Focus

bull What caused the mass extinction during Precambrian Time

bull Essential Question What things first appeared in the Precambrian Time and became dominant during the Paleozoic Era

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull What caused the mass extinction during Precambrian Time

bull Essential Question What things first appeared in the Precambrian Time and became dominant during the Paleozoic Era

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull Gymnosperms dominated the land

bull

bull __Gymnosperms____are plants that produce seeds in cones like pine cones

bull

bull _Angiosperms____ are flowering plants which first appeared during at the end of this era

bull Time marked by rapid movements of plates

bull Scientists hypothesize that possibly a large _asteroids__ or _comets__ impacted with Earth

Mesozoic Era

bull Dinosaurs were also very active in this erandash First small dinosaurs appeared in the Triassic

Periodndash Larger and more abundant dinosaurs

bull What caused the mass extinction during Precambrian Time

bull Essential Question What things first appeared in the Precambrian Time and became dominant during the Paleozoic Era

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

Mesozoic Era

bull Dinosaurs were also very active in this erandash First small dinosaurs appeared in the Triassic

Periodndash Larger and more abundant dinosaurs

appeared in the Jurassic Period

bull Small mammals and birds also appeared during this erandash The mammals were small warm-blooded

animals Hair covering their bodiesbull These characteristics help them survive in

changing environments

Mesozoic Era

bull The main plant life of this time were Gymnosperms or plants that produce seeds but no flowers ndash Pine Trees

bull Angiosperms are Flowering plants that during the END of this era

Mesozoic Era

bull This era ended with a mass extinction event about 65 million years agondash Many groups of animals including the dinosaurs

disappeared suddenly at this time

bull Many scientists believe that this event was caused by a comet or asteroid colliding with the Earth

Mesozoic Era ndash Mass Extinction Event

bull Asteroid or Comet collides with Earth

ndash Huge cloud of smoke and dust fills the airndash Blocks out sunlightndash Plants diendash Animals that eat plants diendash Animals that eat plant-eaters die

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull What does the law of superposition states

bull Essential Question

bull What information in the geologic record might lead scientists to infer that shallow seas covered much of the Earth during the Paleozoic Era

Cenozoic Era ndash Recent Lifebull Began about 65 million years ago and continues

todayndash Climate was warm and mildndash Marine animals such as whales and dolphins evolved

bull Mammals began to increase and evolve adaptations that allowed them to live in many different environments ndash land air and the seandash Grasses increased and provided a food source for grazing

animals

bull Many mountain ranges formed during the Cenozoic Erandash Alps in Europe and Himalayas in India Rocky Mountains in

the USA

Cenozoic Erabull Growth of these mountains may have helped to

cool down the climatendash Ice Ages occurred late in the Cenozoic Era

(Quaternary Period)

bull As the climate changed the animals had to adapt to the rise and fall of the oceans caused by melting glaciers

bull This era is sometimes called the ldquoAge of Mammalsrdquo

Cenozoic Erabull Marine animal examples

ndash Algae Mollusks Fish and Mammals

bull Land animal examplesndash Bats Cats Dogs Cattle and Humansndash Humans are thought to have appeared around 35

million years ago (during the most recent period ndash Quaternary)

bull Flowering plants were now the most common plant life

Cenozoic Mammals

Flowering Plants were common during the Cenozoic Era

bull Which two eras of Earths history ended with major extinctions of species due to a catastrophic event such as an asteroid or comet

bull bull A Precambrian and Paleozoicbull B Paleozoic and Mesozoic bull C Paleozoic and Cenozoicbull D Mesozoic and Cenozoic

Essential Question

bull How would you explain how the Earths history has been influenced by climatic changes

Falcon Focus

bull What caused the mass extinction during Precambrian Time

bull Essential Question What things first appeared in the Precambrian Time and became dominant during the Paleozoic Era

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Page 110: Falcon Focus What is the saying for Natural Selection? Essential Question: How would you explain the connections between eons, eras, periods, and epochs?

Essential Question

bull How would you explain how the Earths history has been influenced by climatic changes

Falcon Focus

bull What caused the mass extinction during Precambrian Time

bull Essential Question What things first appeared in the Precambrian Time and became dominant during the Paleozoic Era

5 Question Quiz

1 Which era is the age of dinosaurs

2 Which era is the age of trilobites

3 Which era is the age of mammals

4 What is the connection between periods eons eras and epochs

5 Give 2 facts about the Precambrian Time

Standard

bull 8-23 Explain how Earthrsquos history has been influenced by catastrophes (including the impact of an asteroid or comet climatic changes and volcanic activity) that have affected the conditions on Earth and the diversity of its life-forms

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Page 114: Falcon Focus What is the saying for Natural Selection? Essential Question: How would you explain the connections between eons, eras, periods, and epochs?

Impact of an asteroid or comet

bull What is the difference between asteroids and comets The main difference between asteroids and comets is what they are made of Asteroids are made up of metals and rocky material while comets are made up of ice dust and rocky material Both asteroids and comets were formed early in the history of the solar system about 45 billion years ago

bull Asteroids formed much closer to the sun where it was too warm for ices to remain solid Comets formed farther from the sun where ices would not melt Comets which approach the sun loose material with each orbit because some of their ice melts and vaporizes to form a tail

Impact of an asteroid or comet

bull Earthrsquos atmosphere protects the planet from many of the meteors that enter it resulting in their burning up before striking the surface

bull At the end of the Mesozoic Era when reptiles early birds and mammals thrived many groups of animals disappeared suddenly

bull Scientists hypothesize that possibly a large asteroid or comet impacted with Earth

bull This impact caused dust and smoke to rise into the atmosphere and cause climatic changes as well as the dying of many forms of plant life and animals that depended on those plants for food

bull A major life form that disappeared at this time was the dinosaur

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes

Climatic changes

bull Earthrsquos environments have many different climates even today Climate is an ever-changing condition on Earth

bull Earliest life forms were influenced by the climates produced by the forming atmosphere and oceans of Earth

bull

bull bull Life on land developed and flourished in

the tropical climates and warm shallow seas during the Paleozoic Era Throughout this era as different land environments formed and sea levels changed new life forms developed Other life forms that could not adapt or find suitable conditions especially many marine species disappeared

bull During the Mesozoic era many climate changes occurred due to plate tectonics and the movement of landmasses Plants and animals that survived through this time had structures and systems that allowed for greater adaptations such as seed coverings for plant seeds and protective body coverings or constant internal temperature for animals

bull During the present Cenozoic era climate conditions continue to change Major ice ages caused the climate to become much cooler as ice sheets and glaciers covered many areas of Earth Many mountain ranges formed causing climate differences due to elevation and due to location near those ranges

bull

Volcanic activity

bull From the earliest days while Earth was forming to present day volcanic activity has been part of the nature of this changing planet

bull During the Precambrian time volcanic activity was one of the most natural events but lava flows ash clouds in the atmosphere and heat made conditions for life forms extremely difficult

bull As continent collided and mountains built up due to plate tectonics volcanoes also formed What type of boundary stress and fault is this __________________________________

bull Volcanic activity continued to be common in the Paleozoic era During the rapid movement of plates in the Mesozoic era collisions and subduction produced extensive volcanic activity around plate boundaries

bull Plate boundaries are still the location of much of Earthrsquos volcanic activity

bull Very explosive volcanic activity can send ash and dust high into the atmosphere where it is carried great distances around the Earth The Sun can be blocked for long periods of time This violent type of activity can disrupt many of Earthrsquos processes and ultimately the life forms that depend on those processes

bull

bull The eras of Earth history can be studied in light of conditions on Earth the effect of those conditions on life-forms and the possibilities of rapid changes to both (environmental conditions and life forms) due to catastrophes
