How Mountains Are Made

Taking a Closer Look at the Earth

Fold Mountains

Fold mountains are a very common type. They are created when two continental plates push into each other. The continental crust of the Earth is forced up over a long period of time gradually forming a mountain. This usually happens when is a water basin between the two mountains, but is not always the case. An example of a fold mountain are the Himalayan Mountains.

Block Mountains

Block Mountains are formed when faults in the Earth's crust force some material up or down. These mountains aren't as common as fold mountains, but they are still one of the top three. An example of a fault block mountain is the Sierra Nevada mountains in North America.

Volcanic Mountains

Volcanoes are formed when magma from the Earth's mantle makes it's way up to the surface. Eventually the magma will erupt from the Earth's surface. Every times there is an eruption, the volcano gets bigger.
