How old is Earth?

Gradual change in living things over long periods of time

Scientists who study fossils

Preserved remains or traces of a once living organism

No longer exists and will never again live on Earth

All of the information that paleontologist have gathered about past life

Geological process that happened in the past are explained by current geological processes

Which rocks are fossils generally found in

Fossils of warm climate plants have been found in Antarctica. What conclusion can be made based on this evidence.

A fossilized structure that formed in sedimentary rock by animal activity (tracks, burrows, animal dung)

Rocks are broken down into small pieces

Process by which sediments settle or drop out of wind or water

Process in which sediments move from one place to the another by water, wind, ice or gravity

Fossils (from Classical Latin fossilis; literally, obtained by digging) are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement

Fossils can help scientist make inferences about Earth's prehistoric surface, climate, and organisms
