1. 1 Oklahoma: Land of Contrasts Chapter 2: Where in the World is Oklahoma? (and why do I need to know this?)

2. Section 1: What is geography?  study of the physical features of the earth and how the environment affects humans.  shapes the way people live, the jobs they do, the food they eat, the clothes they wear and more.  Studies how people affect their surroundings.  As people expanded across the land - they clear forests, dam rivers, introduce new species of insects, plants, and animals, and destroy some native plants and animals.

3. “If you don’t like the weather…wait ten minutes, it’ll change” Will Rogers How does geographic location affect our state?

4. Location, Location, Location!!!!  Located between 94º 29' and 103º W longitude.  Also lies between 33º 39' and 37º N latitude.  1829 Missouri Compromise: set the 36º 30' N latitude as the boundary where slavery could exist – included the territory that became our state

5. Latitude – horizontal like the rungs on a ladder “laddertude” Longitude = the long part of the ladder – going up

6.  94º 29' and 103º W longitude.  33º 39' and 37º N latitude.

8. Oklahoma Geography Statistics  Nearly 70,000 square miles (69,903 sq. miles)  1224 square miles covered by water  Over 10 million acres are cover by forest  Most of the state is part of a giant oval grassland that extends from Canada to Mexico.  Known as the Great Plains and for many years the Great American Desert, it acts as a barrier between the species of the eastern and western forest regions.
