Two processes a rock must undergo before becoming an igneous rock are melting, where the rock is heated to a point where it turns into magma, and cooling, where the magma solidifies to form an igneous rock.
The two types of igneous rock are are intrusive and extrusive, depending on where they form. Intrusive igneous rock forms underground from slow cooling magma. Extrusive igneous rock forms at or near the surface from quick cooling lava.
