Differences between relative chronometric dating techniques

Relative dating is a scientific process of evaluation used to determine the relative order of past events, but does not determine the absolute age of an object.

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.

The difference between relative dating and absolute dating is that relative dating is a method of sequencing events in the order in which they happened.

Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques.

The primary difference is that absolute dating assigns an actual time or age to an event or object.

Both are attempting to get information on the history of events.

For example, 60 million years is a measure of absolute time. These are numerical representations of time, and they give us specific points of reference.

We have a long record of events in absolute time but much of that occurred before humans were on Earth to write it down.

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.
