The principle of cross-cutting relationships states that certain features, such as faults, are than the rock layers they cut through. These features are breaks in Earth’s surface where rock has moved sideways, upward, or downward. formations are made of molten rock that has cooled. Those on Earth’s surface are called . Those beneath Earth’s surface are called .
By the principle of cross-cutting relationships, a feature that cuts through rock layers formed after those layers. Therefore, the faults are younger than the layers they cut through; the correct choice is younger.
