Mountains are formed , when tectonic plates ( a layer of the earths crust ) move and collide to be pushed up in big folds or blocks. Mountains are formed over the course of millions of years but they form very slowly. However, they are not all the same. Have you ever wanted to know how many types of mountains there are ?

 Block mountains

Block mountains begin to form when a slab of land breaks off and is forced up as two of the tectonic plates pull apart or push together. Faults are lines were the ground  breaks apart. As two of the Earths tectonic plates move, a big slab of hand breaks off. The blocks on either side of the block mountain are forced down while the mountain is forced up.

Dome mountain 

Dome mountains occur when liquid rock inside the earth forced the ground above it upward this swelling doesn’t break through the surface. The amount of force pressure makes a dome like shape. The Milton rock , does not erupt through the crust like volcano.Dome mountains don’t usually get as high as folded mountains.

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