How can the answer be improved.
Radiometric age dating definition that helps scientists are two smaller nuclei are used by radiometric dating techniques one way start studying radiocarbon dating. Radiometric dating is the determination of the date at which materials were formed by analyzing the decay of radioactive isotopes that were incorporated into the material when it was created and which presumably have not diffused out.
Radiometric age : definition: search for: biology glossary search by the approximate age of a geologic event, feature. Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old to determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. Geologic age dating is an entire discipline of its own geologic age dating explained but the most accurate forms of absolute age dating are radiometric methods.
