The sun helps form fossil fuels by

• giving energy to organisms that become fossil fuels

• heating up the water in the ocean to cause evaporation

• heating up the earth's core to form fossil fuels

Which is the first step in the formation of oil?

• marine organisms die in the ocean and get buried

• ocean currents carry organic matter to deeper waters

• marine animals eat smaller ones

The formation of fossil fuels takes approximately

• 100 to 500 years

• 1000 to 5000 years

• millions of years

Fossil fuels need this to form.

• heat and pressure

• heat, pressure and time

• pressure and time

Fossil fuels form in sedimentary rocks when

• sediments turn into oil

• organic matter is squeezed by heat and pressure over time

• rivers deposit organic matter downstream
