The model below 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? Options: 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.
