Relative vs radioactive dating
WebSep 21, 2024 · Radiometric dating is a method used to date rocks based on the known decay rate of radioactive isotopes. This method works because rocks are radioactive. Now, they do not give off enough radiation ... WebRadiometric 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 …
