Era of Natural Texas and Its PeopleEra of Natural Texas and Its People
• What is an era? A fixed period of time characterized by particular events, features, developments, or people.
• Why do historians divide history into eras? Historians divide history into eras in order to create blocks of time that have similar characteristics in order to organize and present information about the past.
Era of Natural Texas and Its PeopleEra of Natural Texas and Its People
• TEKS 1A– Identify the major eras in Texas history, describe their
defining characteristics, and explain why historians divide the past into eras, including Natural Texas and its People; Age of Contact; Spanish Colonial; Mexican National; Revolution and Republic; Early Statehood; Texas in the Civil War and Reconstruction; Cotton, Cattle, and Railroads; Age of Oil; Texas in the Great Depression and World War II; Civil Rights and Conservatism; and Contemporary Texas
6 Geographical Questions6 Geographical Questions• Location – Where is it?
• Place – What is it like?
• Regions – How does it compare to other places?
• Human-Environment Interaction – How do humans react to their environment and how does it affect them?
• Human Systems
• Physical Systems
LocationLocation – Where is it?– Where is it?• Absolute Location – The exact location
of a place on the earth’s surface
• Relative Location – The location of a place in relation to other places
• The Absolute location and Relative location of Texas affect it in many ways – How has Texas’ relative location to Mexico affected it? (Left Column) *Turn and talk to a partner

PlacePlace – What is it like?– What is it like?• Place refers to the physical and
human characteristics of a location
• Physical Characteristics include:– Landforms, Climate, plants, animals
• Human Characteristics include:– Language, Religion, Architecture,
Music, Politics, ways of life

• Geographers divide areas into regions in order to better study them.
• Regions are places that are united based on common characteristics
• Regions can be based on physical, human, business and other characteristics

Human-Environment InteractionHuman-Environment Interaction How do humans react to their environment
and how does it affect them? Use, adapt to or change.
• Ex: Pollution
Deforestation
Hurricanes/Tornadoes
Farming
Damming Rivers to make lakes
• Texans have adapted and modified the environment by:– building dams on rivers to harness power for
electricity.– irrigating the farms in the Great Plains region
to yield sufficient crops such as cotton, wheat, rice, corn, etc.
Human SystemsHuman Systems• Movement - How people move through
the environment
• Cultural Diffusion - new ideas brought by migrating people become widely accepted. Examples?
• People bring ideas and goods with them when they move from one place to another.
Physical SystemsPhysical Systems• Geographers analyze physical systems
such as mountains, volcanoes, hurricanes, glaciers to see how they interact with and shape places and regions.
• They also study plant and animal ecosystems that depend on each other and their surroundings in places and regions for their survival.

Roy BedichekRoy Bedichek
He was an author and speaker; considered a “Naturalist”
who traveled and
documented the
Texas landscape for
over 30 years. Died in
1959.
Texas has the most varied climate of any other state in the U.S. It even varies greatly from
one area of the state to the next.
Absolute LocationAbsolute Location• Texas lies in what are called the middle latitudes,
the region about midway between the equator and the north pole.
• Because of this absolute location of Texas being not very far north of the equator, it has mild winters, and because it
is not very far south of the north pole is has mild summers.
NorthersNorthers• Sudden, icy blasts of cold air, called
northers, extend south from Canada and sweep across the plains of Texas.
• Despite its overall warmth, Texas is subject to periods of cold weather.
StormsStorms• Violent storms form when cool air from the north
collides with moist warm air from the Gulf of Mexico.
• Because Texas is on the Gulf, destructive storms such as hurricanes sometimes sweep across the state.
Relative LocationRelative Location• Because Texas is on the gulf coast, breezes
from the Gulf of Mexico cool Texas in the summer and warm it in the winter.
• Moisture from the Gulf gives Texas a lot of its rainfall. However,
some parts of Texas are so far from The Gulf it has little effect on climate there. In the hot, dry areas, water is a precious, natural resource.
ElevationElevation• Elevation also affects
the Texas climate. The temperature cools by 3 degrees every 1000-foot rise in elevation.
• The temperature rises as elevation decreases
