Mountains!
Presentation by Ryan and Billy
Types of Mountains
• Folded mountains• Fault-block mountains• Volcanic mountains• Dome mountains• Erosion mountains
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.
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.
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.
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.
Mt. Shasta
• Located in California.
• Elevation is 14,180ft.

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

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