Rocks

Rock formed when lava or magma cools, forms crystals, and solidifies.

• Sedementary Rock

• Metamorphosis Rock

• Mineral Cementation

• Igneous Rock

The cycle through which Earth's rocks change from one type into another over time due to various Earth processes; creates changes in mineral compositions and physical structures.

• Mineral Cycle
