The age of the 1. FOSSILS is determined by 2. NEUTRONS or radioactive dating technique in which the 3. HALF LIFE of carbon and found 4. RADIOMETRIC elements is determined to calculate the 5. AGE of fossil or the rock.Today's knowledge of fossil edge comes primarily from radiometric dating,also known as 6. RADIOACTIVE DATING .Radiometric dating relies on the properties of isotopes.These are chemical elements,like 7. CARBON or uranium,that are identical except for one key feature-the number of 8. RADIOACTIVE in their nucleus.
