Question

How are fuels such as coal and petroleum formed?

Answer 1

1. Coal and petroleum are fossil fuels.
2. Fossil fuels are the dead remains of plants and animals buried deep under the Earth millions of years ago.
3. Fossil fuels are formed under the conditions of high temperature, high pressure, and lack of oxygen.
4. These fuels are non-renewable energy sources as they cannot be replenished.
5. The usage of fossil fuels is more than the formation. It takes millions of years to form again.

Hence the fuels such as coal and petroleum are formed from the dead remains of plants and animals buried under the soil.
