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.
