ROCK TELLS

A STORY

Rock covers Earth. It tells a story.

When we study rock, we can learn

about Earth’s past. We can also

understand its future.

How do we learn about life from the

past? Plant and animal remains can get

covered by sediment. They get cast in rock.

These are called fossils. We study them.

We learn about what once lived here.
