Petroleum meaning

Petroleum definition

Raw material from which gasoline , kerosene, lubricating oils, propane , diesel fuel, etc. are refined. Consists primarily of hydrogen and carbon ; but also contains other elements. Its source is decomposed organic matter which has been buried. Some used to think that the action of ice ages moved soil over great forests of tropical vegetation. The current suggestion is that great bodies of water flooded tropical vegetation in a cataclysmic event.
