Answer the following question given this paragraph: The best-known method of radiometric dating is carbon-14 dating . A living thing takes in carbon-14 (along with stable carbon-12). As the carbon-14 decays, it is replaced with more carbon-14. After the organism dies, it stops taking in carbon. That includes carbon-14. The carbon-14 that is in its body continues to decay. So the organism contains less and less carbon-14 as time goes on. We can estimate the amount of carbon-14 that has decayed by measuring the amount of carbon-14 to carbon-12. We know how fast carbon-14 decays. With this information, we can tell how long ago the organism died. Q: Carbon-14 dating is a method of what kind of dating? Choices: - orbital - stratigraphy - metamorphic - radiometric A:
(A).
radiometric
