Presentation Transcript

  1. Types of Mountains • Folded • Fault-block • Volcanic • Unwarped

  2. FOLDED MOUNTAINS http://www.cssd11.k12.co.us/dohnts/images/earth/fldmtn.jpg

  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.
