Question

1. how are fossil fuels formed? what is required?

Explanation:

Fossil fuels (coal, oil, natural gas) form from the remains of ancient plants and animals. Over millions of years, these organic materials are buried under sediment. Heat and pressure from geological processes transform them. Requirements include organic matter (from dead organisms), sedimentary burial, time (millions of years), heat, and pressure. For example, coal comes from plant matter in swamps; oil and gas from marine organisms in ocean sediments.

Answer:

Fossil fuels (coal, petroleum, natural gas) form from the remains of ancient plants/animals. Over millions of years, organic matter is buried under sediment, then transformed by heat, pressure, and time. Requirements: organic material (dead organisms), sedimentary burial, long time (millions of years), heat, and pressure.
