These notes are a supplement and are in no way a substitute for what happens in class. In class there are activities and exercises that involve application of the material. The test will involve not only memorization of facts but also the application and use of those facts in a meaningful manner. This is higher order learning and more relevant to the “real world”.
|Landforms, Mountains, and Maps|
There are three main landforms:
Plains are large flat areas of lands that have only small changes in elevation.
-There are 2 types of plains:
Low large flat areas of lands along the coast
Made from deposits of silt and sediment
Have Rich fertile soil good for farming ( cotton,citrus,fruits...)
Ex.Atlantic Coastal Plain/, Gulf Coastal Plain
Low large flat areas of lands located inland on a continent
Have a higher elevation than coastal plain
Made from the deposits from the hills and mountains
Have good soil for farming (wheat oats barley) Bread basket
Flat grassy dry areas
Ex. Great Plains - Nebraska, Kansas, Arkansas
A plateau is a large, flat area of land that is higher than the surrounding land (raised).
Uplifted by earth's forces
Look like plains but with a higher elevation
Dry desert like areas ofton used for animal grazing
Ex. Colorado Plateau
A mountain is a very tall high, natural place on Earth - higher than a hill. It has high elevation, narrow peaks andstep sides. The tallest mountain on Earth is Mt. Everest.
There are 4 types of mountains:
|Folded Mountains are caused by pressure being applied from both or one side. In the diagram , you can see that the pressure forces the mountains to bend and fold. On the top of the mountains, several different layers are exposed as a result of eriosion. Appalachiansn|
|Formed when blocks of Earth's crust are pushed
pressure directly beneath the land, southern Rockies, Adirondacks
|Huge tilted slabs of rock break due
to pressure and slide past one another (along fault planes), Grand Tetons in WY, Sierra Nevadas in CA
|Form when molten material reaches the surface through a weak area in the crust. Mount St. Helens|
