Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

Radiometric dating involves dating rocks or other objects by measuring the extent to which different radioactive isotopes or nuclei have.
