Fossil fuels are the fuels formed by natural processes such as the decomposition of dead and buried organisms.
Coal, Petroleum, and Natural gas are some of the fossil fuels.
Fossil fuels cause pollution because the combustion of fossil fuels adds poisonous gases like sulphur oxides, nitrogen oxides, carbon monoxide, and particulate matter.
The poisonous gas produced fills in the atmosphere and is life-threatening to the living organism.
The nitrogen oxides produced by fossil fuels are released into the atmosphere, which contributes to the formation of smog and acid rain.
