Relative age dating examples
Relative dating is the science of determining the relative order of past events (ie, the age of an object in comparison to another), without necessarily determining their absolute age, (ie estimated age.
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.
