What role do faults play in the Law of Superposition?

• Faults create new types of rock.

• Faults are younger than the layers they cut through.

• Faults are the same age as the layers they cut through.

Why are index fossils used as guides to determine the age of rocks?

• Each index fossil lived during a specific geologic time period.

• All index fossils lived during all the periods of geologic time.

• Index fossils are very rare and are not commonly found in rocks.
