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.
Which mountains were formed by the collision between continents? Numerous mountain ranges were formed by the collision of two continental tectonic plates, including the Himalayas, the Alps, the Appalachians and the Atlas mountains. It is also thought that the Rocky Mountains formed in part due to small pieces of land on the Pacific oceanic plate colliding with North America.
