WebJan 15, 2008 · In relative dating, fossils are compared to similar fossils and rocks, the ages of which are known. Absolute dating, on the other hand is used to calculate the precise age of fossils through radiometric dating. This process measures isotope decay inside the fossil or the rock to determine its exact age. WebJul 10, 2013 · Over time, carbon-14 decays radioactively and turns into nitrogen. A living organism takes in both carbon-12 and carbon-14 from the environment in the same relative proportion that they existed naturally. Once the organism dies, it stops replenishing its carbon supply, and the total carbon-14 content in the organism slowly disappears.
