Final answer:
Coal is formed at the bottom of swamps, oil is formed at the bottom of the ocean, and natural gas is formed when sediment, rock, and water apply pressure and heat to the organic matter.
Step-by-step explanation:
Coal: Formed at the bottom of swamps
Oil: Formed at the bottom of the ocean
Natural gas: Sediment, Rock, and water apply pressure and heat
All three types of fossil fuels are formed from organic matter that was buried, heated, and subjected to pressure over millions of years. Coal is formed at the bottom of swamps, oil is formed at the bottom of the ocean, and natural gas is formed when sediment, rock, and water apply pressure and heat to the organic matter. Additionally, carbon bonds break to produce methane, which is the primary component of natural gas.
