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.
A fossil fuel is any hydrocarbon that may be used as a source of  energy. Coal, oil and natural gas are the three basic fossil fuels,  formed 300 million years ago from orga â¦ nic plant and animal life  subjected to great heat and pressure under the ground. They are  classes as non-renewable sources of energy.ossil fuels contain high percentages of carbon  and include coal, petroleum, and natural gas. When the carbon in  the fuel is burnt with oxygen from the atmosphere, the energy that  was used in photosynthesis is released and carbon dioxide is  re-formed.
