Geological rock cycle. Diagram showing the cycle in the Earth's crust between different types of rock. This cutaway artwork shows a subduction zone where heavier oceanic rock (right, purple-brown) is descending under continental rock (light brown, left) and being destroyed to form molten rock (red-orange) and volcanoes. Above ground, erosion of mountains carries sediment along rivers to the sea, forming sedimentary rocks. The nine basic stages are: magma; rock crystallization; igneous rocks; erosion; sedimentation; sedimentary rocks; tectonic burial and metamorphism; metamorphic rocks; and melting.
