A rock that forms from other rocks due to heat and pressure beneath the Earth's surface is called a metamorphic rock. Examples include marble, slate, and gneiss.
As depth beneath the Earth's surface increases, both temperature and pressure increase. This is due to the weight of the overlying rock and the Earth's internal heat. The increase in pressure and temperature with depth is known as the geothermal gradient.
