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.

However, carbon dating is an absolute dating technique that can give an estimate of the actual age of an artifact and thus an estimate of the age of other objects in the same layer.

Similarly, relative dating is done by paleontologists who find layers of fossils.

Overtime, the C-14 atoms give off radiation, and, eventually, transform into nitrogen-14 atoms.

The term used to define the amount of time it takes for half of the radioactive atoms, such as C-14, in a body or object to decay fully is known as a "half-life." The half-life of C-14 is approximately 5 730 years.

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.

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.
