Radiometric dating is a technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products.
Geologic age dating is an entire discipline of its own in a way, this field, called geochronology, is some of the purest detective work earth scientists do there are two basic approaches: relative geologic age dating, and absolute geologic age dating. Clocks in the rocks then radioactive dating would be extremely reliable since the radioactive half-life of a given isotope is quite independent of any natural. Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object relative.
