Volcanic rocks have two types: intrusive rocks and extrusive rocks. Intrusive rocks, also known as plutonic rocks, form when molten magma cools and solidifies underground. Extrusive rocks, also called volcanic rocks, form when molten lava erupts onto the Earth's surface and cools quickly.

Underground = intrusive/plutonic aboveground = extrusive/volcanic
