It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age.This is possible because properties of rock formations are closely associated with the age of the artifacts found trapped within them.Relative dating is determined by comparing its placement with that of fossils in other layers of rock.Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.Absolute dating, on the other hand is capable of telling the exact age of an item using carbon dating and many other techniques that were not there in earlier times.Relative dating makes use of the common sense principle that in a deposition of layers.

Relative dating is achieved by determining the position of rock in strata, and the appearance of certain index fossils.A layer that is higher is of later age than a layer that is lower in order.This means that the oldest are the strata that are lying at the bottom.It is possible to tell the number of years ago a particular rock or archeological site had been formed.Two broad categories of classification methods are relative dating and absolute dating.
