Fossil Fuels - There are coal, crude oils, oil shales, tar sands and natural gases such as butane, ethane, methane which occur naturally from the decomposition of plant and sea and land organisms over millions of years. Burning fossil fuels is the major way in which humans add to the greenhouse gases in the atmosphere.
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.ossil fuel combustion results in the emission of carbon dioxide,  which is a heat trapping greenhouse gas.    Volcanic activity releases some hundred million tons o â¦ f CO2 into  the atmosphere each year.
