Although absolute dating methods determine the accurate age compared to the relative methods, both are good in their own ways. Absolute dating, also called numerical dating, arranges the historical remains in order of their ages. Using Absolute Dating Methods Determine the material makeup of the object being dated. To find their age, two major geological dating methods are used. Something is dated relatively using methods of stratigraphy, linguistic dating and climate chronology to name a few.
