What is the difference between relative and absolute age? Relative age is the age of a rock layer (or the fossils it contains) compared to other layers. It can be determined by looking at the position of rock layers. Absolute age is the numeric age of a layer of rocks or fossils.

How do relative dating and absolute dating differ in determining the age of stratified rocks?

Methods to Determine the Age of Stratified Rocks There are two methods of determining the ages of rocks: relative dating and absolute dating. Relative dating is a method of arranging geological events based on the rock sequence. Absolute dating is a method that gives an actual date of the rock or period of an event.
