Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.Many people have been led to believe that radiometric dating methods have proved the earth to be billions of years old.Radiocarbon Basics Carbon comes in three “varieties” or isotopes: C is 5,730 years.Because carbon is expected to be thoroughly mixed throughout the biosphere, atmosphere, and oceans, living organisms (which continually “take in” carbon throughout their lifetimes) are expected to have the same C in their bodies begins to decrease.Half the original quantity of carbon-14 will decay back to the stable element nitrogen-14 after only 5,730 years.
