All Types Of Fossil Fuels. These are coal oil and natural gas. Fossil fuels principally consist of carbon and hydrogen bonds.
Natural gas is a mixture comprised mostly of hydrogen carbon and methane. The organic matter takes centuries to form. It is thought that these are formed from decomposition of dead waste of plants and animals for millions of years.
The fossil fuels on earth were formed well before the presence of dinosaurs which is why they are called fossil fuels.
Decomposing plants and other organisms buried beneath layers of sediment and rock have taken millennia to become the carbon rich deposits we now call fossil fuels. The coal can be thought to as the solid state fossil oil as the liquid state fossil and natural gas as the gaseous state fossil. There are three types of fossil fuels which can all be used for energy provision. Petroleum or crude oil.
