The former gives a numeric age (for example, this artefact is 5000 years old); In archeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates. Absolute dating measures the presence and ratios of chemicals within the rocks to determine the number of years since they were deposited.
For relative dating, the layer of rocks becomes one example where the top rock is the newest one, and the bottom rock stays the oldest. When used as an adjective, is it used to mean final and not liable to modification.

Prior to the discovery of radiometric dating in the early.
