The [[Rock Cycle]] has several stages:
*[[Weathering]] - Rocks are broken down by the [[environment]].
*[[Erosion (Rock Cycle)|Erosion]] - Wearing away rocks into smaller pieces.
*[[Transport (Rock Cycle)|Transport]] - Small pieces of rock are moved by rivers, glaciers and the wind.
*[[Deposition (Rock Cycle)|Deposition]] - When water and the wind slow down or when glaciers melt the small pieces of rock fall to the ground.
*[[Sedimentation]] - Layers of [[sediment]] (small pieces of rock) build up on lake beds and sea beds.
*[[Compaction]] - So many layers build up that the [[pressure]] squeezes all the water out.
*[[Cementation]] - [[Mineral]] salts that were [[dissolve]]d in the [[water]] fall out of [[solution]] and bind the [[sediment]] together.
If the rocks get buried deep enough:
*Heat and Pressure - The rock is either changed by the heat and pressure into a [[Metamorphic]] rock or the rock is [[melted]] to become [[magma]].
*[[Uplift]] - Pressure from underneath the rock causes it to rise to the surface.
*Volcanoes - The molten rock comes out of [[volcano]]es as [[lava]] before it freezes to become an [[Igneous]] rock.
