Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.

The importance of radiometric dating is that it allows us to tell how old some things are.

For instance, in radiocarbon dating, there really isn't a way to date something to 100,000 years or more. The Jurassic is an age that began about 200 million years ago and stretched for about 50 million years to about 150 million years ago.Elements exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will spontaneously change into a different nuclide by radioactive decay.The decay may happen by emission of particles (usually electrons (beta decay), positrons or alpha particles) or by spontaneous nuclear fission, and electron capture.The method works best if neither the parent nuclide nor the daughter product enters or leaves the material after its formation.
