How does absolute dating compare to relative dating? Absolute dating is a method of estimating the age of a rock sample in years via radiometric techniques. It relies on a natural phenomenon that is the foundation of life on earth. On the other hand, absolute dating includes all methods that provide figures about the real estimated age of archaeological objects or occupations.
