petroleum, rock oil (mid-14c. in Anglo-French), from Medieval Latin petroleum, from Latin: petra : rock + oleum : oil. ) is a naturally occurring, yellow-to-black liquid found in geological formations beneath the Earth 's surface, which is commonly refined into various types of fuels.
Oil and natural gas together make petroleum. Petroleum, which is Latin for rock oil, is a fossil fuel, meaning it was made naturally from decaying prehistoric plant and animal remains.
