Answer

Answer:

dates the remains of organisms to determine when they died

Brief Explanations:

Carbon - 14 dating is a radiometric dating method. Organisms take in carbon - 14 during life. After death, the carbon - 14 decays at a known rate. By measuring the remaining carbon - 14, the time since the organism died can be determined. Nitrogen - 14 does not decay into carbon - 14; it's the opposite. It's mainly for dating organic remains, not ancient volcanic rocks, and is not typically used for fossils older than about 50,000 years as the amount of carbon - 14 becomes too small to measure accurately.
