Placing of events in the order in which they occurred without any relationship to the actual time during which any one event occurred is known as relative dating. It is a qualitative way of describing the sequence of events.

How do the basic principle of relative dating differ from one another?

Relative dating cannot establish absolute age, but it can establish whether one rock is older or younger than another. Relative dating requires an extensive knowledge of stratigraphic succession, a fancy term for the way rock strata are built up and changed by geologic processes.
