There are various reasons for the formation of the mountains.
------quote-----
Mountains are formed by volcanism, erosion, and disturbances or uplift in the earth's crust.Majority of mountains are formed by geological forces heat and pressure producing changes under the earth's crust and movements in the earth's crust. They call this movement plate tectonics.Other processes are caused by horizontal compression that is the deformation of crustal strata which produces folds or wrinkles. The Himalayas, for example, were raised by the compression that accompanied collision of the Indian plate with the Eurasian plate.Some ranges of low mountains are raised by nontectonic processes, and are caused by sculpturing effects of differential erosion.Example-Mount Ranier and Mount Saint Helens in the United States and Mount Fuji in Japan.
