Bones are the most likely part of an organism to become a fossil due to their hard structure.

Front

What are the two traits of the best index fossils?

Back

The best index fossils are widespread geographically and have a short lifespan.

Back

The youngest layer is the one on top (Layer A).

Front

True or False: To be considered an index fossil, it had to have lived for a relatively short period of time.

Front

What is an index fossil?

Back

An index fossil is a fossil that is used to define and identify a particular time period in the geological time scale.

Front

What is the significance of the law of superposition?

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water.

Front

What is the difference between relative dating and absolute dating?
