Folded Mountains

The Folded Mountains form when rock layers are squeezed together , and pushed upward.

An example of a Folded Mountain range that formed at a convergent boundary.

Other examples of mountain ranges that consist of very and complex folds are the Alps in central Europe , the Ural Mountains in Russia , and the Himalayas.

Fault-Block Mountains

Fault-Block Mountains forms when this tensions causes large blocks of the Earths crust to drop down relative to other blocks .

When sedimentary rock layers are tilting up by faulting , they can produce mountains that have sharp , jagged peaks .

For example , the Tentons in western Wyoming are a spectacular of the Fault-blocking Mountains.

Volcanic Mountains

Volcanic Mountains are rocks that is melted in subduction zones form magma , which rises to the Earths surface and erupts .

Volcanic Mountains can also form under the sea, which sometimes rises above the ocean surface to become islands/land .

Volcanic Mountains on the Earth have formed around the tectonically active rim of the Pacific Ocean.
