The WEST The Geography A vast region • Largest region in the U.S • 11 States • This region also includes Hawaii and Alaskaour largest state Vast Region • Vast-meaning different landforms • Snow capped mountains to fiery volcanoes • Deserts to thick forests Plants and animals • Because of the vast region-many types of plants and animals • Bears, eagles, blue columbine, frangipani Mountains • The rocky mountains-young mountains that stretch more than 3, 000 miles • Formed from huge plates, that floated and bumped into each other and slid upward • The Rockies get lots of snow! • http://www.youtube.com/watch?v=tJk9cFz152s Rivers • As the snow from the Rockies melts, it flows into the Rio Grande, the Missouri River and the Colorado River The Great Salt Lake • Rivers and stream flow into this lake • Brings freshwater and salt • This lake is getting smaller because of evaporation • Saltier than the ocean-too salty for fish • http://www.youtube.com/watch?v=ZxL_0VfUPQ A A region in motion • Earthquakes-ground trembles • During an earthquake-the plates bump each other and push together-common on the west coast because plates are close together! • http://www.youtube.com/watch?v=zNyVPsj8zc • http://www.youtube.com/watch?v=T0AEtXuPLA Volcanoes • Magma-melted rock pushes through the earth’s plates • When the magma reaches the surface-its called lava • http://www.youtube.com/watch?v=u2V2kAG p91I Hot Spots • Some volcanoes form from hot spots or places where magma reaches the earths surface but doesn’t break through http://www.youtube.com/watch?v=EeaQbqcZNMw Geyser • Pressure from the steam under the water builds up and shoots hot water or steam into the air-OLD FAITHFUL http://www.youtube.com/watch?v=_gyhvqbIaOE Climate in the west • The elevation affects the climate-higher up you go the colder it gets • Timberlines-tree lines Alaska and Hawaii climate • • • • It is far away from the equator Has cool summers and very cold winters Hawaii is closer to the equator Warm, tropical climate Precipitation • Very wet area around Washington -160 inches of rain every year
