Fossil fuels form when organic matter which has been buried in the Earth over a long period of time is subjected to heat and pressure over a long period of time. Heat and pressure are both critical components for the formation of a fossil fuel. The process of the formation of fossil fuel is the same today as it was in the past. The geological processes are the same for the formation of fossils.
