Answer: The fault is younger than the layers of rock, according to the law of crosscutting.
Explanation:
Then Law of Crosscutting which was described by James Hutton explains that whenever a fault is seen on a rock, the fault will always be younger than the rock it is one.
This makes sense because if there was no rock in the first place, the fault would not have cut through it. But because there was a rock and an object exacted a force in order to move through the rock, the fault appeared showing that the rock came first, then came the fault.
