In the Florida map shown below, use the law of superposition to determine which rocks are oldest? Map of Florida identifying fou
r different kinds of rock strata. The top layer of quaternary rock is labeled A; the bottom layer of quaternary rock is labeled B; the top layer of tertiary rock is labeled C; the bottom layer of tertiary rock is labeled D. Public Domain A B C D
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.
