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 layers, while radiometric dating uses data from the decay of radioactive substances within an object. Relative dating observes the placement of fossils and rock in layers known as strata.
Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.
