Answer: Relative dating to determine the age of rocks and fossils. Geologists have established a set of principles that can be applied to sedimentary and volcanic rocks that are exposed at the Earth's surface to determine the relative ages of geological events preserved in the rock record.

In relative dating, we determine which things are older or younger based on their relationships. For example, we know from geology that soil layers near the surface of the ground are usually younger than those deeper down.

The principle of superposition is simple, intuitive, and is the basis for relative age dating. It states that rocks positioned below other rocks are older than the rocks above.
