Igneous rock is formed from the cooling and solidification of magma or lava.

Metamorphic rock is formed when existing rocks are subjected to heat and pressure.

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

The three major types of rocks are Igneous, Metamorphic, and Sedimentary.

Intrusive igneous rock has large crystals because it cools slowly beneath the Earth's surface.

Cementation is the process where sediments are pressed together and bind to form sedimentary rock.

Intrusive igneous rocks form inside the Earth and cool slowly, while extrusive igneous rocks form on the surface and cool quickly.

Sandstone is an example of a sedimentary rock.

The rock cycle is the continuous process of rock formation, breakdown, and reformation.

Metamorphism is the process by which existing rocks are transformed by heat, pressure, or chemically active fluids.
