Your welcome for helping you with Biology Homework.... Both are attempting to get information on the history of events.Tools like radiometric dating use radioactive isotopes and known decay rates… relative is determining the relative order of past events, without necessarily determining their absolute age.Similarly, relative dating is done by paleontologists who find layers of fossils.By deducing which fossils are formed in the sequence of time, the periods when the particular fossilized entities existed can be arranged in order without the actual dates of when the fossils were laid down.Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains.Relative dating, meanwhile, measures the order of past events, without determining their absolute age.

Radiometric dating, based on known rates of decay of radioactive isotopes in objects, allows a specific age of an object to be determined to some degree of accuracy.

Short Answer: The term relative dating is distinguished from absolute dating to make it clear that one does not get a specific estimate of the age of an object from relative dating, but one does get such an estimate of true age from absolute dating.

There are several techniques employed in both sets of methods. Long Answer: Sciences such as geology, paleontology and archeology are very interested in identifying the age of objects found and these scientists sometimes use both relative dating or absolute dating to characterize the age of the objects they study.

The primary difference in relative dating and absolute dating is that absolute dating assigns an actual time or age to an event or object. Relative dating involves the dating of geological events and formations that occured/existed throughout the whole geological history, and this eventually gives the relative age of the earth.

While, Absolute dating involves the use of isotopes and radioctive elements (radioactivity) and also the study and relation of meteorites and moon rocks, which eventually gives the actual/absolute age of the earth.

Absolute dating of rock is achieved by radiometric dating techniques.
