Igneous, sedimentary, and metamorphic.

Igneous rocks are formed from the cooling and solidification of magma or lava.

Intrusive igneous rocks form inside the Earth, while extrusive igneous rocks form on the surface.

Metamorphism is the process by which rocks change due to heat, pressure, or chemically active fluids.
