Billy is looking at a diagram of rock layers. He says that the oldest rock layers are always found at the top. Is Billy correct?
Yes, Billy is correct. The oldest rock layers are always at the top. Newer rock layers form underneath them.
No, Billy is not correct. The oldest rock layers are at the bottom. The newer rock layers form on top.
