  2. Landforms • 3 basic types • Plains • Plateaus • Mountains

  3. Plains • Plains • Large flat areas • 2 types: • Coastal plains • Interior plains

  4. Plains • Coastal Plains • Exposed region of the continental shelf. • The continental shelf is the part of the continent that extends into the ocean. • Size varies over time with changes in sea level. • Characterized by low hills, swamps, and marshes.

  5. Plains • Interior Plains • Found in the interior of continents. • Thick, fertile soil.

  6. Plateaus • Plateaus • Flat, raised areas of land with steep sides. • Consist of horizontal layers of rock that have been slowly uplifted. • Often cut by canyons formed by rivers.

  7. Mountains • 4 Types: • Folded • Upwarped • Fault-Block • Volcanic

  8. Mountains • Folded Mountains • http://howard.nebrwesleyan.edu/hhmi/fellows/gbrand/mtbld.htm • Consist of folded rock layers. • Formed by horizontal forces (rocks are squeezed together) • Examples, • Alps, Himalayas

  9. Mountains • Upwarped Mountains • Formed when blocks of crust are pushed up. • Examples: • Black Hills, Adirondacks

  10. Mountains • Fault-Block Mountains • Huge tilted blocks of rocks with faults on the side. • Examples: Grand Teton, Sierra Nevada

  11. Mountains • Volcanic Mountains • Formed by volcanism. • Examples: Hawaii, Mount Shasta
