The Carbon 14 (C-14) dating method is a radiometric dating method. A radiometric dating uses the known rate of decay of radioactive isotopes to date an object. Each radioactive isotope has a known, fixed rate of decay, which we call a half-life.

Which best describes the process of carbon 14 dating?

Carbon-14 decays at a constant rate, and scientists measure the amount of carbon in a fossil to determine its age. Scientists compare the Carbon-14 levels in present humans with human fossils.
