Sedimentary rocks
Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organisms. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. Sedimentary rocks are classified into three groups: Clastic, Biologic, and Chemical.

Metamorphic rocks
Metamorphic rocks form when high temperatures and pressure act on a rock to alter its physical and chemical properties. These conditions often stretch, twist, and fold the rock as it cools. In metamorphic rocks some or all of the minerals in the original rock are replaced, atom by atom, to form new minerals.
