... becoming melted at some depth by the tremendous heat and pressure. Some of of this molten rock or magma returns to the surface, melting some continental crust in the process, sometimes reaching the surface as volcanoes and lava flows. Mountain ranges are created from the formation of these deep magmas and the effects of volcano-building. When continental crust ...
