Geologic age dating—assigning an age to materials—is an entire discipline of its own. In a relative dating of one method Describe this field, called geochronology, is some of the purest detective work earth scientists do.
There are two basic approaches: Here is an easy-to understand analogy for your students: Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old. To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. Relative dating of one method Describe is called the Rule of Superposition.
This rule is common sense, but it serves as a powerful reference point.

Geologists draw on it and other basic principles http: Relative age dating also means paying attention to crosscutting relationships. Say for example that a volcanic dike, or a fault, cuts across several sedimentary layers, or maybe through another volcanic rock type.
