What do the processes of the formation of sedimentary rocks and fossil fuels have in common?

• Sedimentary rocks are the only type of rock where fossils are found that produce energy.

• Sedimentary rocks and fossil fuels are mixed with fossils to provide energy.

• Fossil fuels and sedimentary rocks are burned to release energy.

• Sedimentary rocks and fossil fuels are both formed over a long period of time with high pressure.
