dating when men have job problems - Compare and contrast relative and absolute dating
The base layer must come first, then the second and then the third.
So I can say the second layer is younger than the first and older than the third but I have no idea whether the cake is 5 minutes or 5 million years old.
Two of the most well-known and most frequently used include radioactive dating and relative dating. Organic bodies, such as you and me, as well as inanimate objects, such as stone tablets or rocks.
Phrased simply, radioactive dating is the method that uses measurements relating to the radioactivity of the atoms in a fossil or an artifact. What "decay" means is that the atoms in the object or body become unstable, and, over time, begin to "decompose" by giving off radiation in the forms of subatomic particles (such as electrons and protons).
Much in the same way used to approximate the age of organic fossils, scientists use uranium-238's decay rate and the uranium-238 to lead-206 (which it decays into) ratio to approximate an age to assign to the object.
