Rock Cycle

Weathering and Erosion

Weathering and erosion is something that is inevitable. Weathering is when wind, or water wears away parts of the rock into a new shape. Erosion is when wind or water picks up and moves the rock or rock pieces to another place.

Transport and Deposition

Is when a rock is moved to another place and laid down.


Sedimentation is when pieces of sediment concrete and compact together and they become one single sediment rock. It will only separate with weathering and erosion.

Compaction and Cementation  

Compaction is when pieces of sediment are pushed together with mass pressure and heat so they combine together and become one rock. Cementation is when sediment pieces cement together with pressure  and heat to make on or more rocks out of the thousands or million pieces of sediment.

Sedimentary Rock

Sedimentary rock is lots of sediment pieces  cemented, compacted, combined together into one rock. It can be weathered and eroded back into sediment pieces as it was before the full rock formation.

Metamorphic Rock

Metamorphic rock is when another type of rock is buried under ground and kept there with high temperatures and mass amounts of pressure under the Earths surface then it becomes a metamorphic rock.

Burial, high temperature & pressure

This is how a metamorphic rock is formed by being buried under the Earths surface and having high pressure and temperatures making it a metamorphic rock.


Melting is when a rock is at such high temperatures and pressure that it melts into magma.

Magma from molten crust & mantle

Magma is formed from melted rock which is molten crust and mantle.


Magma is melted rock below the Earths surface if it was above then it would be lava because it is above the Earths surface.

Intrusive Igneous Rock

Intrusive igneous rock is when magma cools under the Earths surface in magma chambers and it cools slowly.

Extrusive Igneous Rock

Extrusive igneous rock is when it cools fast above or on the Earths surface.
