Sedimentary Rock Process Concept Check

Coal, petroleum, and natural gas are all fossil fuels. Fossil fuels originated from —

• buried, dead organisms changed by heat and pressure

• heat preserved within Earth’s crust

• decayed rocks from within Earth’s crust

• plants that survived Earth’s changes

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.

The model shows layers of sediment on the floor of an ocean. Which of the following best explains how these layers can become rock over many years? (5.7A)

• Sand in the sediment melts and turns into rock.

• The weight of the water compacts the sediment into rock.

• Changing water temperatures turn sand in the sediment into rock.

• Pollution caused by humans turns the sediment into rock.
