WebMountains are some of the most impressive natural structures on earth. Yet how are these massive ridges in the Earth’s crust formed?The process that creates mountains is the large-scale movement of the Earth’s tectonic plates or the earth’s crust.. This movement can be broken up into different processes such as volcanic activity, folding, and faulting.
