Organic rocks are not a type of rock. They are formed from the remains of living organisms.

Deposition is the process by which sediment is deposited and forms new rock.

Metamorphism is the process by which rocks are changed from one type to another by the action of heat, pressure, and chemical reactions.

Organic fossils are not a type of fossil. They are the remains of living organisms.

The Hadean Eon is the period of time during which the Earth was formed.

Organic structures are not a type of geological structure. They are formed by living organisms.

Erosion is the process by which the Earth's surface is shaped by the action of wind, water, and other natural forces.

Organic resources are not a type of natural resource. They are formed from the remains of living organisms.

The rock cycle is the process by which the Earth's crust is recycled.

Organic boundaries are not a type of plate boundary. They are formed by living organisms.

Plate tectonics is the theory that explains the movement of the Earth's tectonic plates.
