Together with natural gas, it makes up petroleum, which is Latin for rock oil. Petroleum is basically a mix of naturally occurring organic compounds from within the earth that contain primarily hydrogen, carbon and oxygen. When petroleum comes straight out of the ground as a liquid it is called crude oil if dark and viscous, and condensate if clear and volatile. When solid it is asphalt, and when semi-solid it is tar. There is also natural gas, which can be associated with oil or found alone. Crude oil comes in many forms. Usually it is black, but green, red or brown oils are not uncommon. Thin and volatile oils are called light, whereas thick and viscous ones are heavy. Light oils have an API gravity of 30 to 40 degrees, which means that the density is much less than 1.0 g/cc.
