The three kinds of rocks by their method of formation are IGNEOUS rocks, SEDIMENTARY rocks and METAMORPHIC rocks.
Igneous rocks cool from magma or lava.
Sedimentary rocks form by the deposition of particulates and silt.
Metamorphic rocks form from rocks (usually sedimentary) that are compressed and heated underground.
