Igneous Rocks and the Rock Cycle
www.dnr.sc.govIgneous rocks are formed by the cooling of molten rock. There are two major states of molten rock: Magma and Lava. Magma is a form of molten rock that exists below the Earth’s surface. Lava is the term given to magma once it reaches the Earth’s surface, usually in the form of a volcanic eruption.
Sedimentary Rocks and the Rock Cycle
www.dnr.sc.govSedimentary rocks are formed by the lithification of inorganic and/or organic sediments, or as chemical precipitates. There are two types of sedimentary rocks: Clastic and Chemical Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,
