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

FAULT-BLOCK MOUNTAINS

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.

VOLCANIC MOUNTAIN NAMIBIA IN AFRICA

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.

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.

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