How mountains are formed

Mountains are formed from the Earth crust, which is pushed up in big folds(forced) up and down in blocks. Slowly of the course of millions of years, mountains begin to form. Although they are all mountains they are not all the same. There are lots of types of mountains, which are called block, dome, volcanic and each mountain belongs to a mountain range.

Block mountains

Block mountains are  are formed when a(large) flat piece off land breaks off and is forced up by tectonic plates. Two off the earth tectonic plates pull apart or push together and make the mountains in a block like shape. The faults break the ground apart and when there are earth quakes the tectonic plates push up and make the block mountains.

Dome mountain

Dome mountains take place when a liquid rock inside the earths, it forces the ground above it and pushes upward because of the tectonic plates. The (liquid in the rock) swelling doesn’t break through the surfaces. The forces or pressure in the liquid rock pushes together and make a dome like shape.

 

A brilliant information page on mountains and how they are formed. Great use of subheadings and pictures.
