The following are the major methods of relative dating radiometric dating: this technique solely depends on the traces of radioactive isotopes found in fossils the rate of decay of these. Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods relative dating uses observation of location within rock. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, all radiometric dating methods measure isotopes in some way.
