Crude oil is a fossil fuel derived from marine plants and animals that died millions of years ago, before the dinosaurs. In its liquid form, crude oil can be found underground in reservoirs, sedimentary rocks, and tar sands.

Crude oil has been used to produce petroleum products such as gasoline, waxes, and plastics. It has also been heavily used in manufacturing, industrialization, and transportation. Since crude oil is found in certain geological areas, some countries are more likely than others to be sitting on large oil reserves.
