Science: Geology: Earth Systems, Fossilization

Introduction to Geology: Walter Alvarez introduces geology and discusses how the physical features of Earth can tell us about its history.

Apatosaurus Fossilization is the process of bones hardening into rock. When a animal dies it's body rots away and the only thing that's left is it's bones. After a while soil starts to cover up the bones.  The sediment in the soil hardens on the bones and the bones become rock. These bones are called fossils,scientists who study fossils are called paleontologists they go on digs to uncover the bones and when they get back they study them.
