Proving once again how shallow and indecisive women are.. Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbonin 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. Consent (BDSM) Together with stratigraphic principlesradiometric 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.One of the most commonly used methods for determining the age of fossils is via radioactive dating (a.k.a. absolute dating). This method involves comparing the ratio of radioactive isotopes in the fossil to that found in the atmosphere today. Radioisotopes are alternative forms of an element that have the same number of . Discover how scientists determine the age of fossils, rocks and other geologic phenomena by using the known half-lives of isotopes within each.
