what are fossil fuels list the various types of fossil fuels
Answers
Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.
There are three main fossil fuels: coal, petroleum and natural gas. Coal is cheap and abundant, but it releases a lot of pollutants when burned. Petroleum, or crude oil, is harder to find and is typically a bit cleaner-burning — and, unlike coal, it can be pumped through pipelines and easily refined into fuels like gasoline or kerosene. Natural gas is also relatively inexpensive and less polluting than coal or crude oil.

Fossil fuels are the remains of prehistoric plants and animals which got bury deep inside the earth million of year ago due to some natural process.
Formation of fossil fuels :-
Million of year ago see covered off much of what is now dry land .
In Prehistoric times tiny people and animal lived in the sea. When these died they send to the bottom of the sea and God buried in layers of mud and sand. As the ages past the organic materials and deeper and deeper. The earth's crust change its shape and put intense pressure and heat on what were the only plants & tiny animal. Heat from the earth's interior and the weight of the overlying rock gradually changes this energy containing substances and two oil or fossil fuels .
