Mountains form in different ways: Sometimes the crust has folded and buckled, sometimes it breaks into huge blocks. In both cases, great areas of land are lifted upwards to form mountains. Other mountains are formed by the earth's crust rising into a dome or by volcanic activity when the crust cracks open.

Mountains are formed through varying causes; there are several distinct types of mountains. Changes to mountains usually take place very slowly, over millions of years. On the other hand, some changes, such as an eruption of a volcano (right) happen suddenly and violently.

Mountains began to take shape five hundred million years ago when the surface of Earth was still forming. A thin layer of rock known as ‘crust” covers the land and the ocean bed. Powerful forces deep under Earth’s surface caused the crust to break in places and form the plates, or giant pieces. Earth’s plates are like giant pieces of a jigsaw puzzle. They float around slowly on red-hot liquid that lies below the crust layer. At their edges, or margins, plates are pushed together. Mountains form along the margins of Earth’s plates. The plates bump against each other with so much pressure that the land at the margins is squeezed together. As the plates keep pushing, the land at margins can only move upward. It forms huge folds in Earth’s surface.
