Carbon-14 dating, also called radiocarbon dating, method of age determination that depends upon the decay to nitrogen of radiocarbon (carbon-14). Because carbon-14 decays at this constant rate, an estimate of the date at which an organism died can be made by measuring the amount of its residual radiocarbon.

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.
