Volcanic mountains are formed when magma erupts from the Earth's crust and hardens into a mountain shape. Dome mountains form when magma pushes up from below the crust but cannot break through, instead warping the crust into a dome shape under high pressure. Fault-block mountains are created when a crack in the Earth's crust closes suddenly, raising one side into a mountain with a steep front and sloping back.

2. Volcanic Mountains How they are formed A volcanic mountain is formed when magma hurls itself up from the earth and hardens in the form of a mountain. Lava and Magma White hot liquid rock is called magma when it inside the volcano or earths crust but lava when it is outside.

3. Dome Mountains How they are formed Dome mountains are formed sort of like a volcano. Magma pushes itself up from the earths crust , but the upper crust is too strong for the magma to break through, so it bends the earth up into a semi-sphere shape in an attempt to break through, there is a high amount of pressure on the upper crust, so if it were to break, it would be an extremely powerful eruption. What they are Dome mountains are chunks of warped earth that were pushed up into dome shapes by the white hot magma below the surface.

4. Fault-Block Mountains How are they formed? Fault block mountains are made when a fault (crack) in the earth suddenly closes and a fault block mountain is raised from the crack. What they are Fault block mountains are mountains that have a steep front and side and a sloping back side.
