Absolute- actual age of a rock relative- the age of something compared to other things relative age does not tell how old something is but tells us in what order events have happenedrelative- the age of a rock or fossil compared to the surrounding rocks and fossil. Relative dating cannot establish absolute age, geologists establish the relative ages of rocks mostly through their understanding of stratigraphic succession.

Absolute age is the age of a geologic formation in years unlike relative age, which determines whether a formation is older or younger than its surrounding formations, absolute age provides geologists with the actual age of a formation radiometric dating examines the radioactive isotopes in an .
