The process of forming a Volcano

The volcano is formed face of the earth caused by tectonic events. Volcanoes are formed in the area of the collision plate oceanic crust and continental crust. In the region where the collision plate is formed fault zone. Part plates are destroyed, will melt due to contact with hot magma from the bowels of the earth. Remelting would be a volcanic magma. Furthermore, the magma volcano will break out of the earth surface and form volcanoes.
