Fossil fuel s-fuels derived from the remains of dead organisms. Examples include coal, oil, oil shales, tar sands, natural gas, and peat. Hydrocarbon s are molecules that incorporate both carbon and hydrogen. When hydrocarbon molecules are exposed to heat, the bonds linking the carbon and hydrogen atoms break.
Where Fossil Fuels Come From. There are three major forms of fossil fuels: coal, oil and natural gas. All three were formed many hundreds of millions of years ago before the time of the dinosaurs â hence the name fossil fuels. The age they were formed is called the Carboniferous Period.
