Question

Fossil fuels are formed from:

• A. The solidified lava originated from volcanic eruptions
• B. Living organisms buried inside the Earth for millions of years
• C. Burning of wood with the limited oxygen supply
• D. The washing down of rocks by water flow for millions of years

Answer 1

The correct option is B

Living organisms buried inside the Earth for millions of years

Fossil fuels such as coal and petroleum are formed by the dead remains of living organisms which were buried under the Earth crust for millions of years. Burning of wood with the limited oxygen supply would result in charcoal, which is not a fossil fuel.
