Welcome to Science 11/1Welcome to Science 11/1Put your name on your paper. Divide it into 4

sections as shown below. This is your 1st quarter evaluation. Answer each question honestly, this will help make class better for you.

What do you like best about this class?

What activity/procedure that we do on a regular basis helps you learn best?

What is one thing you would change to help make this class better?

What is one thing you need to do differently in order to improve your grade this quarter?

Review (Earth’s Layers)Earth’s layers can be categorized in two ways:

Compositon and Physical Crust LithosphereMantle AsthenosphereCore Mesosphere Outer Core Inner Core

Review (Plates)Earth’s lithosphere is broken up into several

massive pieces called tectonic plates that move on top of the asthenosphere (upper mantle)

Review (Convection Currents)Convection Currents in the Mantle cause

Earth’s plates to move. These currents are caused by heat from the core.

The higher the temp. the lower the density.

Review (plate movement)Plates move in three different ways: 1. converge (come together) 2. diverge (move

apart) 3. transform (slide past each other)

Review (plate movement effects)When Earth’s plates move several process can

happen such as: sea-floor spreading, subduction, mountain building, faulting, earthquakes, and volcanoes.

ReviewAll of the concepts we have learned to this point

are closely related to each other.These science concepts are like a puzzle: All of the

“pieces” work together to make something bigger.The concepts are also an example of cause &

effect. When one process occurs another process will occur in return.

EXPERIMENT of THE DAYYou are eating at a restaurant when you spill

your glass of water on an empty plate. The server comes by to help you clean it up, but before the water gets cleaned up, the server says that he will give you your meal for free if you can get the water back into the glass with out lifting the plate up. He says you can use the lemon that was in your water and matches.

What do all of these things have in common?

They are all made of

rock?

Why are rocks important?Since the beginning of human existence,

we have depended on them.

How did rock form on Earth?Not only do we rely on rock for tools and

construction, but Earth’s crust, which supports human life, is made of solid rock.

So, how did Earth’s crust form?The early Earth was originally a giant ball of

magma & lava. As Earth cooled down, some of the magma & lava hardened to form Earth’s crust.

Early Earth

Ch. 4 Section 1: Understanding RockWhat is rock?A solid mixture of minerals.Why is it important?We live on rock and we use rock for many things.

The Rock CycleThe processes that can change rocks into different

types of rocks.

What do all of these items have in common?

Rock ClassificationComposition- What something is made of. The

minerals a rock is made of determines its composition.

A rocks color is an indication of the rock’s mineral composition.

Rock ClassificationSome rocks are smooth and shiny. Others are

rough and dull. What do geologists call the look and feel of a rock’s surface?

TextureFine Grained-Medium Grained-Coarse Grained

What are the 3 major groups that geologists classify rocks into?1. Igneous2. Sedimentary3. Metamorphic

Igneous Rock Igneous rock-

form from the cooling of magma or lava.

Can form on or beneath Earth’s surface.

Sedimentary RockSediment- small,

solid pieces of material that come from rocks or living things.

Most sedimentary rocks are formed through a series of processes.

From Sediment to RockErosion- running water, wind, or ice loosen

and carry away fragments of rock.

From Sediment to RockDeposition- the process by which sediment

settles out of the water or wind carrying it.

From Sediment to RockCompaction- the process that presses

sediments together.

From Sediment to RockCementation- process by which sediments

are glued together and hardened.

Metamorphic RockMetamorphic rock- created when heat and

pressure deep beneath Earth’s surface change any rock into metamorphic rock.

Homework OptionsComplete the Ch. 5 WorksheetWrite a poem or song about the 3 types of

rocks. (Must tell what the three types of rock are and how they are formed. Poem or song must be appropriate and make sense.)

Illustrate one of each of the types of rock and write a short paragraph describing what they are and how they formed.

(Illustrations must be detailed, match the shape, color and features of the rocks.)
