Igneous Rocks - Rocks formed through the cooling and solidification of magma or lava. Sedimentary Rocks - Rocks that are formed by the deposition of material at the Earth's surface and within bodies of water. Metamorphic Rocks - Rocks that have been modified by pressure, temperature, and chemical processes within the Earth's crust.

Rocks are classified by how they were formed and their composition. Igneous rocks form when molten material cools and hardens. Examples of igneous rocks include basalt, obsidian, and granite. Sedimentary rocks form when layers of sediment press together. Examples of sedimentary rocks include sandstone, shale, and limestone. Metamorphic rocks form when heat and pressure change existing rocks. Examples of metamorphic rocks include marble, quartzite, and schist.
