Mountain Types


The Five Basic Mountain Types:

1)Fold Mountains (Folded Mountains)

2) Fault-block Mountains (Block Mountains)
3) Dome Mountains
4) Volcanic Mountains
5) Plateau Mountains

Fold Mountains

Most common mountain type. They are formed when two plates collide head on, and their edges crumbled, much the same way as a piece of paper folds when pushed together.

Fault-block Mountains

These mountains form when faults or cracks in the earth's crust force some materials or blocks of rock up and others down.

Dome Mountains

Dome mountains are the result of a great amount of melted rock (magma) pushing its way up under the earth crust.

   
                                                                    Black Dome Mountain 

Volcanic Mountains

Volcanic Mountains are formed when molten rock (also known as lava) deep within the earth, erupts, and piles upon the surface.

Plateau Mountains

Plateaus are large flat areas that have been pushed above sea level by forces within the Earth, or have been formed by layers of lava.
