Comparing Volcanos and Mountains

How are Mountains formed

Over long periods, mountains are created by tremendous forces in the earth with a steep top usually shaped up to a peak or ridge. Mountains occur more often in oceans than land: some islands are the peaks of mountains coming out of the water. Mountains are formed by volcanism, erosion, and disturbances or uplift in the earths crust. Most geologists believe that the majority of mountains are formed by geological forces heat and pressure producing changes under the earths crust and movements in the earths crust. They call this movement plate tectonics. This theory sees the crust of the earth divided into a vast rigid plates that move about at the rate of a few centimeters. The uplift is caused by the collision of plates below the earth
