The three main groups of igneous rocks are intrusive (plutonic), extrusive (volcanic), and hypabyssal rocks. Intrusive rocks form below the Earth's surface from the slow cooling of magma. Extrusive rocks form on the Earth's surface from rapidly cooling lava. Hypabyssal rocks are intermediate rocks that form from magma that solidifies in the crust.
