1. Mountains! Presentation by Ryan and Billy

2. Types of Mountains • Folded mountains • Fault-block mountains • Volcanic mountains • Dome mountains • Erosion mountains

3. Mountain Vocabulary • Fold mountain: created where continental plates collide, thus forcing the crust to crumple and fold. • Fault-block mountain: is a mountain that forms from a block of crust that is pushed upward or downward along a fault. • Volcano: mountains created by magma that escaped from Earth’s interior, then it cools.

4. Mountain Vocabulary (Cont.) • Hot spots: an area of the crust above a rising plume of magma, where volcanic material can erupt through a plate creating volcanic mountains. • Dome mountains: a dome-shaped mound that forms in Earth’s crust.

5. Tall Facts • Mountains are the tallest land form on Earth. • Mountains are not permanent. • Most form at or near plate boundaries mainly where two plates collide. • Mountains folds are common where tectonic plates collide. • Erosion softens and wears down folds.

6. Tall Facts (Cont.) • Some of the oldest fold mountains have rounded peaks such as Arkansas’ Ouachita. • Fault-block mountains occur where ever a faulting occurs. • Fault-block form when pressure splits the crust.

7. Mt. Shasta • Located in California. • Elevation is 14,180ft. Ryan’s cat Shasta

8. Tall Facts (Cont.) • Not all volcanoes erupt. • At divergent boundaries, magma rises up in the gap between the two plates that are pulling apart. • Hot spots are formed by magma plumes rising.

9. Erosion Mountains • Mountains are always being shaped erosion. • Catskills in New York was formed by erosion. • There is only a few amount of erosion formed mountains in the world. • Erosion formed mountains which can result in irregular peaks and valleys.

10. Mt. Fuji • Height is 12,388 ft. • Located on Honshu Island, Japan, which is the tallest mountain in Japan.

11. Mountains of California • Tallest mountain in California is Mount. Whitney. • Mt. Diablo is 3,848 ft. • Mount. Muir is the sixth tallest mountain in California at 14,019 ft.
