What is relative dating?

• used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

• used to determine the precise age of a fossil by using radioactive dating to measure.

• Order of layers from oldest to youngest

• Used to determine the location of the rocks around the world.
