a student observes some different fossils found in the state where he lives. each of these four fossils are found in different sediment layers. the fossils are shown in the picture. after observing the fossils, he claims that the fossils show that the environment in his state has always been in the same as it is now. but his friend argues that his claim is likely incorrect because she thinks these fossils are evidence that the environment has changed in the state in the past. is her argument correct? why or why not?

Answer

Brief Explanations:

Fossils are remnants of past - life forms. Different fossils in sediment layers suggest different past environments. For example, a fish fossil implies a past aquatic environment, which may be different from the current environment. So, the presence of diverse fossils indicates environmental change over time.

Answer:

Yes, her argument is correct. The different fossils in various sediment layers are evidence that the environment in the state has changed in the past.
