Question

When looking at rock layers, fossils are typically _____ at the bottom and _____ at the top

Answer 1

Answer: The oldest layers are on the bottom, and the youngest layers are on the top.

Explanation: Because sediments sometimes include once-living organisms, sedimentary rock often contains a lot of fossils. Fossils are once-living organisms that have been turned into rock, in which the shape or form of the organism can still be seen.
