  2. Section 1 Physical Features I. Landforms A. Barrier islands- long narrow islands created by ocean waves along coasts B. Piedmont-area at or near foot of Appalachian region

  3. C. The east and interior (1) 1. Appalachians contain Blue Ridge, Catskill and Green Mountains 2. Created from collision 3. Weathered down to 6,000 ft 4. Watershed of Mississippi River/Ohio River 5. Glacier once covered northern interior 6. Ozark plateau to south 7. Great Plains 8. North of interior plains-Canadian Shield

  4. U.S. Watershed

  5. Glacial Coverage

  6. Great Plains

  7. D. The West (2) 1. Rockies-14,000 ft 2. Intermountain region-high plateaus and desert basins (Great Basin) 3. Rivers rarely reach the ocean 4. Death Valley-lowest point-282 ft below

  8. E. Pacific Region (3) 1. Sierra Nevada and Cascade Ranges 2. Several volcanoes in Cascades (Rainier, Hood, Shasta and St. Helens) 3. Coast Ranges

  9. 4. Ring of Fire along eastern side of Pacific plate 5. Hawaii formed over hot spot-leaking magma from ocean floor 6. Southern coast of Alaska has a subduction zone where many earthquakes happen. 7. Mount McKinley-20,320 ft

  10. Bodies of Water A. Continental Divide 1. Rockies-divide rivers flowing east and rivers flowing west 2. Rivers in Midwest drain region and provide transportation routes

  11. 3. Mississippi delta 4. St. Lawrence System-connects Great Lakes to Atlantic 5. Many lakes from retracting ice sheets that melted

  12. Section 2 Climates and Biomes • Climates A. Climates in U.S. influenced by latitude, prevailing winds, currents and mountains B. Canada is mostly influenced by latitude C. Page 142 D. Great Plains is home for many natural hazards because of cold/warm air E. Intermountain region lies in rain shadow F. Most of Canada is subarctic G. Tornado Alley

  13. Plants and Animals A. Forests lie in humid areas while grasslands lie in arid areas B. SE and West-hickory, walnut, oak, deer, opossum, raccoon C. Pacific-Redwoods and Douglas firs, black bears, eagles, hawks, salmon

  14. D. SW-desert, Creosote and mesquite bushes, cacti, coyotes, jackrabbits, hawks, snakes E. Midwest-grassland-once bison, https://www.youtube.com/watch?v=Toxd3YRTris

  15. F. Half of Canada and Alaska-boreal forest, spruce, fir, pine, caribou, deer, elk, moose, wolves G. Further north-permafrost, grasses, small shrubs, mosses, lichens H. Southern Florida and Hawaii-tropical

  16. Section 3-Natural Resources • Farming, Forests and Water Resources A. 3% of population farms in U.S/Canada B. Corn, soybeans and wheat from Great Plains C. Alluvial soils from streams or rivers D. Cattle, hogs other livestock E. Wide variety of fruits and vegetables

  17. F. Wood products-forests in SE and Pacific NW G. Largest producers of hydroelectricity H. Major fishing in eastern Canada I. Cod, haddock, lobster and swordfish J. Salmon in Pacific K. Shrimp and shellfish in Gulf of Mexico

  18. Energy and Minerals A. 25% of world’s coal B. Oil is produced in Alaska, Texas, Louisiana and California C. Natural gas in same areas D. Most of Canada’s come from Alberta
