Chapter 1: Views of EarthWe will cover lesson 1: Landforms and lesson 3: Maps
PlainsPlateaus
Mountains
3 types of landforms
Large, flat areas, often found in interior regions of continents
I. Plains
● Ideal for... ○ farming○ grazing animals
● make up ½ of the land area in the US
Plains that are found near the ocean● Atlantic Coastal Plain
○ East coast stretching from NJ to FL
● Gulf Coastal Plain○ southern US - Gulf of Mexico
A. Coastal Plains (lowlands)
● Central portion of the US● flat grassy area with few trees
● Great Plains (high plains)between the Mississippi River and the Rocky Mountains
B. Interior Plains
flat, raised areas of land made up of nearly horizontal rocks that have been uplifted by forces with the Earth.
II. Plateaus
Colorado Plateau within the Grand Canyon has the Colorado River running through it.
Four main types of mountainsa. folded
b. upwarpedc. fault-blockd. volcanic
III. Mountains
the rock layers are folded like a rug that has been pushed up against the wall
A. Folded Mountains
Appalachian Mountains and the Rocky Mountains
Bear Mountain bridge
form when blocks of Earth’s crust are pushed up by forces inside Earth.sharp peaks and sharp ridges
B. Upwarped Mountains
Adirondack Mountains in NY
Rocky Mountains in Colorado and New Mexico
Black Hills in South Dakota
Black Hills National Forest
made up of huge, tilted blocks of rock that are separated from surrounding rock by faults.vertical movement - one rock pushes up while the other pushes down
C. Fault-Block Mountains
Grand Tetons of Wyoming
form when molten rock forms code-shaped structures on Earth’s surface
D. Volcanic Mountains
Mount St. Helens before and after the 1980 eruption
