Sometimes fossils can be found in sedimentary rocks. Which statement best explains why? A. Heat and pressure from deep within Earth cure fossils to form.

B. Lava may flow over an animal or plant; as it cools and hardens, a fossilized rock is formed.

C. Larger rocks are slowly eroded away by the elements on Earth.

D. The remains of dead plants and animals settle to the bottom of an ocean or lake and are covered by mud. Pressure eventually forms these layers into rock.
