Fossils provide information about the layers of rock in which they are found. For example, the fish fossil indicates that the sediments in the surrounding rock were deposited in or near a body of water.

What information does the fish fossil provide about the age of the rock layer surrounding it?

• The rock is younger than the fossil.

• The rock is older than the fossil.

• The rock and fossil are the same age.

• The age of the rock is unrelated to the age of the fossil.
