It is thought that these are formed from decomposition of dead waste of plants and animals for millions of years. Fossil fuels were formed in the earth s crust out of dead organisms that lived hundreds of millions of years ago.
Coal petroleum and natural gas.
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. All contain carbon and were formed as a result of geologic processes acting on the remains of organic matter produced by photosynthesis a process that began in the archean eon 4 0 billion to 2 5 billion years ago. Coal oil and natural gas.
