Fossils fuels include oil (i.e., petroleum), coal and natural gas. One of these is a thick liquid, another a solid and the third a less dense liquid, but they all share a common origin.

As the name implies, these fuels arise from material that was once a part of living things, both animals and plants, in the very distant past. These prehistoric organisms were compressed over a period of millions of years by rocks, but only when temperature and pressure conditions favored the process; that is, only a small fraction of ancient life was converted to fossil fuels today, just as only a small number of prehistoric animals and plants resulted in the formation of fossils that gave today's human paleontologists specific clues about what these organisms, from dinosaurs to giant ferns, looked like and how they lived.

Oil: This fossil fuel is used mainly for heating and transportation, and it is the source of gasoline in its various forms.

It is arguably the single most valuable commodity the world over, and has transformed civilization in a number of
