Physical Regions of the U.S. Coastal Lowlands • Southeastern Maine to Eastern and Southern U.S. to Eastern Texas. – Forests of hickory, oak, pine, and other trees. – Three Subdivisions • The Piedmont – Southern New York to Atlanta. – In the north referred to as the fall line. • The Atlantic Coastal Plain – Piedmont to Atlantic Ocean, New England to Florida • In the south, cotton, vegetables, citrus fruit, and tobacco. • Resorts and Beaches • Gulf Coastal Plain – Florida to Southern Texas • Fertile Farmland • Petroleum and natural gas Appalachian Highlands (Mountains) • Maine to Alabama – White Mts., Green Mts., Cumberland Mts., Allegheny Mts., Great Smokey Mountains Resources • Coal • Iron • Oil Foliage: Forest of Pine, Oak and Maple • Highest Point: Mt. Mitchell in N.C. 6,684 ft Canadian Shield • Area around the Great Lakes – Covered by glaciers as recently as10,000 years ago – Forest of Spruce, and Fir – Many winter outdoor activities Interior Plains • Extends from Appalachians to the Rocky Mountains • Sub Regions – Central Lowlands • From the Appalachian mtns To just west of the Mississippi River. • Rich farmland for soybeans and corn – Great Plains • From the Rocky Mountains to west of the Mississippi • Known to the pioneers as the “ Great American Desert” • Grassland – Bison – Grain Farming – Cattle and sheep ranching Ozark Plateau/Highlands • Between the Central and Gulf Coastal lowlands in Southern Missouri, Northwest Arkansas and Eastern Oklahoma. • Much of the area is poor farming except in the river valleys. • Coal, Iron Ore and other minerals are valuable resources Rocky Mountains • The largest mountain system in North America that extends from Alaska to Southern New Mexico • Known as the Continental Divide, it separates water flowing to the Pacific and Atlantic Oceans. • Forests cover the lower slopes of the mountains and they are the home to many types of wildlife. • Timber, mining and recreation are the important industries of the area. • Some cattle and sheep are raised in the valleys and meadows and crops are grown in the lower valleys. • The highest place is Mt. Elbert in Colorado at 14,433 ft above sea level. Intermountain Region • Located between the Rockies and the Pacific Coast Mountains • Subdivisions: – Columbia Plateau – Colorado Plateau – The Basin and Range Area Columbia Plateau • • Located in Washington, Oregon, Idaho, and Northern Nevada Fertile volcanic soil, best grain and fruit crops in the northwest Colorado Plateau • • Unusual land forms in America such as flat topped rock formations, natural bridges, Grand Canyon Indians lived here in cliff dwellings The Basin and Range Area • The mountain and desert lowlands between the Columbian and Colorado Plateaus • Also known as the Great Basin Includes “Death Valley” the lowest place in elevation in the U.S. at 282 ft. below sea level. The Pacific Coast Mountains and Valleys • The coast from southern California to Alaska • Evergreen forests provide raw material for lumber and paper • Volcanic activity formed the Cascades, Lassen Peak in California and Mt. St. Helen’s in Washington, volcanoes today. • The eastern boundary is the Cascade Range in the north and the Sierra Nevada Range in the south. • The Sierras are granite mountains with many lakes and waterfalls. • The western boundary is the coast range which hassome major harbors such as Puget Sound and San Francisco Bay.
