1. Organic Matter: This is the starting material for fossil fuels. It's primarily composed of dead plants and animals, although some fossil fuels also contain significant amounts of algae and bacteria.
2. Heat and Pressure: Over millions of years, layers of sediment accumulate on top of the organic matter, burying it deeper and deeper. The weight of these sediments creates intense heat and pressure.
3. Time: The process of transforming organic matter into fossil fuels is extremely slow. It takes millions of years for the heat and pressure to break down the complex organic molecules and transform them into simpler hydrocarbons like oil, natural gas, and coal.
These three factors working together, over vast spans of time, ultimately create the fossil fuels we rely on today.
