Sarah's parents dug up a large hole in their backyard to put in a pool. When they dug up the dirt, they found exposed fossils such as coral, fish, and seaweed. What does this tell them about the environment many years ago?
It was once covered by an ocean.

What can fossils be identified as evidence of?
Past living organisms

Certain places in the United States have fossilized plants that are not much different than plants that are alive today. What does this tell you?
The present day climate is not much different than the climate back then.
