Rock Process

These rocks change over hundreds of years in the 5 steps of the rock cycle: weathering, erosion, deposition, compaction, and cementation. Igneous, sedimentary, and metamorphic rocks on the surface of the earth are constantly being broken down by wind and water, and melted into magma

^Igneous Rock^

Extrusive igneous rock is made by magma coming up and cooling on the surface, and intrusive igneous rock is made by magma that has cooled below the surface.

^Sedimentary Rock^

Sedimentary rock is made by material washing down into the water and the layers of material keep piling on top of each other and the pressure presses it into solid rock.

^Metamorphic Rock^

Metamorphic rock is made by igneous rock and sedimentary rock being under pressure and heated by magma underground.
