The four techniques used in absolute dating are radiometric dating, amino acid dating, dendrochronology, and thermoluminescence.Relative dating is the technique used to determine the age by comparing the historical remaining to the nearby 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 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.If the archaeologist finds a sample suitable for carbon dating, then an absolute date may be assigned to an object.Similarly for 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.It is a less advanced technique when compared to absolute dating.

Since it evaluates the exact age of the sample, absolute ageing is also called numerical dating.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.The circumstances of the object may allow one to say that one object is older than another without being able to assign a particular age to the objects.“Relative Dating.” Science Learning Hub, Available Here 1. “Radiocarbon Date Calibration Curve” By Howard Morland – Own work based on information from: Reimer, P.
