Most liquid fuels in widespread use are derived from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust. However, there are several types, such as hydrogen fuel (for automotive uses), ethanol, jet fuel and biodiesel which are all categorized as a liquid fuel.
The most common fossil fuels are coal, oil, and natural gas. Peat, a very young form of coal, and oil shale are types of fossil fuel.hese fuels were formed millions of years ago from plants and animals that died and decomposed beneath tons of soil and rock. These fossil fuels are not fossils like the bones of prehistoric creatures.
