1 Volcanic mountains-Mountains that are caused by volcanic activity are called volcanic mountains. 2  There are two main types of volcanic mountains: volcanoes and dome mountains. 3  Volcanoes are formed when magma erupts all the way to the surface of the Earth. 4  The magma will harden on the Earth's surface, forming a mountain.

In the former type, the mountain has two steep sides, whereas, the tilted type has one steep side and a gentle sloping side.
