Rocks

A geologist is studying three layers of sedimentary rock in an area. The layers have not shifted from their original positions. The geologist records the relative ages of the rocks. What did the geologist use to determine the relative ages of the rocks?

• Radioactive dating

• Mineral content

• Absolute dating

• The Law of Superposition
