The model above shows layers of sediment on an ocean floor. Which of the following can explain how these layers can become rock over many years?

• sand in the sediment melts and turns into rock

• weight of the water compacts the sediment into rock

• changing water temperatures turn sand in the sediment into rock

• pollution caused by humans turns sediment into rock
