Relative dating simply says one is older than the other but no age is specified.

Tools like radiometric dating allow some samples to be assigned a certain age to within some accuracy.

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.

Free 5-day trial You may not associate geology with time, but the former greatly depends on the latter.

For example: If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of once civilization were found to have been build on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates.

Assigning a certain age or date is a form of absolute dating.

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

Very often historical evidence is found in layers and older layers are further down that the top layers.

For example: If an archaeologist is studying past civilizations, the archaeologist may be able to say that in a particular location the ruins of one civilization were found to have been built on another and so the layers unearthed in an excavation convey the sequence of historical occupations without revealing the actual dates.

Before radiometric dating (or other methods of absolute dating like counting tree rings) it was difficult to determine the actual age of an object.
