Generally, sports, that geologists to date take on relative dating and explain the word absolute dating places events or older than another. Absolute dating, also called numerical dating, arranges the historical remains in order of their ages. One argument in favor of the absolute dating methods presented in the preceding articles is that they should work in principle. The following are the major methods of relative dating.

Although absolute dating methods determine the accurate age compared to the relative methods, both are good in their own ways. For this reason, many archaeologists prefer to use samples from short-lived plants for radiocarbon dating. Relative Dating Techniques Explained.
