Answer:
The answer is A
Explanation:
You can tell that rocks are older or younger depending on if other layers overlap. B is the oldest because all the others cover it, C is the second youngest because D and A overlap it. From what I could tell, when I took the test, it was either A or D, neither overlap each other so I was not sure so I guessed A and got it right. Though it could be looked at that A is smaller than D since its still growing and building.
