1. Types of Mountains
Folded
Fault-block
Volcanic
Unwarped

2. FOLDED MOUNTAINS

3. FOLDED MOUNTAINS
Appalachian Mountains in the eastern United States, and the Swiss Alps in Switzerland
form when two plates collide head on, and their edges crumble
consist mainly of sedimentary rocks, like limestone and shale

4. FAULT-BLOCK
MOUNTAINS

5. FAULT-BLOCK MOUNTAINS
Consist of huge blocks of the earth's crust that have been tilted or pushed up along a fracture line called a fault
Sierra in California, Arizona is an example.
Created when a plate hits a fault and tips upside down, creating erosion and debris, which is at the base of the mountain.

6. VOLCANIC MOUNTAIN
NAMIBIA IN AFRICA

7. Volcanic mountains
Formed when molten rock, or magma deep within the earth, erupts, and piles upon the surface
Made of basalt and rhyolite.
Takes place where two of the earth's tectonic plates collide.

8. UNWARPED MOUNTAINS Black Hills in South Dakota
form when tectonic forces lift the earth's crust into a broad bulge or dome raising it above its surroundings
Erosion causes peaks and valleys to form.

9. largest single mountain in the world
30,000 +feet above the ocean floor
100 miles across at its base.
