the illustration here shows rock layers in their original order, along with a fracture in some rock layers caused by an earthquake. based on the evidence in the illustration, when did an earthquake occur? after rock layer z was deposited before rock layer w was deposited after rock layer y was deposited before rock layer x was deposited

Answer

Brief Explanation:

The earthquake - caused fracture affects Rock Layer V, Rock Layer W, and Rock Layer X but not Rock Layer Y and Rock Layer Z. This means the earthquake occurred after Rock Layer X was deposited and before Rock Layer Y was deposited. Among the given options, the closest correct one is that it occurred after Rock Layer Y was deposited is incorrect as it should be before Y. The only option that makes sense is that it occurred after Rock Layer X was deposited. Since the closest option to this correct logic among the given ones is "After Rock Layer Y was deposited" (as it implies after X and before Y is a closer approximation among these choices).

Answer:

After Rock Layer Y was deposited
