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.

How are sedimentary rocks formed?

• by hardening and cementing of layers of sediment

• by fossils getting buried in various layers of sediment

• by cooling and hardening of hot molten rock from inside the Earth

Which is the best example of an index fossil?

• corals found in rock layers worldwide

• dinosaur bones found only in Australia

• footprints of different types of dinosaurs

• casts of bird feathers found in all layers of rock in an area

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.
