What conditions in an ancient environment would make it suitable to the formation of fossil fuels?

• Movement of surface water.
• Frequent volcanic eruptions.
• Extreme high and low daily temperatures.
• Ancient organisms that are buried beneath layers of sediment.

The formation of fossil fuels is a process that takes millions of years and starts with energy from the Sun. The Sun contributes to the formation of fossil fuels by –

• heating up Earth's core.
• generating wind.
• giving energy to living things that become fossil fuels.
• giving off heat and causing seasons.
