Volcanism is the process by which molten rock material is moved from one part of the earth's crust to another, or from within the earth's crust to the surface. This molten material is called *magma* while it is still beneath the surface, but it is called *lava* as soon as it reaches the surface. All this molten rock material eventually cools and solidifies into igneous rock.
