Relative Dating Techniques Explained. The difference between relative dating and absolute dating is that relative dating is a method of sequencing events in the order in which they happened. Absolute dating, also called numerical dating, arranges the historical remains in order of their ages. However, not all fossils or remains contain such elements.
