The rock cycle shows that any rock can turn into any other type of rock.
- Through the process of HEAT & PRESSURE, igneous and sedimentary rock become METAMORPHIC rock.
- Through the process of WEATHERING & EROSION, metamorphic and igneous rock become SEDIMENTARY rock.
- Through the process of MELTING, sedimentary and metamorphic rock become IGNEOUS rock.
Erosion: the process by which the surface of the earth is worn away by the action of water, wind, glaciers, and waves.
Weathering: the various mechanical and chemical processes that cause exposed rock to decompose (ie: rain, wind, freezing and melting).
Sediment: particles of rock that have been broken down by weathering and erosion.
