Term for a resource such as coal, oil, or natural gas formed from ancient organic matter?

• A. Renewable energy
• B. Fossil fuel
• C. Nuclear energy
• D. Biomass

Answer: (B)

These resources are fossil fuels because they come from the remains of ancient plants and microorganisms that were buried and transformed by heat and pressure over millions of years. Coal forms from ancient swamp vegetation, while oil and natural gas come from marine organisms that settled in sediments. Their energy content is very high, which is why they have been so important for power and transport, but they are non-renewable since their formation takes geologic timescales. Once burned, they don’t quickly replace themselves. In contrast, renewable energy sources like solar and wind replenish more quickly, and biomass uses contemporary plant or animal material which can be renewable if managed sustainably. Nuclear energy relies on radioactive materials and is not derived from ancient organic matter, so it isn’t a fossil fuel either.
