When magma, which is molten rock, cools, igneous rock forms. This can happen as a subsurface event, or it can occur as exposed magma solidfies at the surface after it emerges. The number of different "types" of rock that are formed are as varied as the material from which it forms, and are also affected by the way the rock cools. Use the link below and pick up more information at Wikipedia.
