Absolute and relative dating in geology

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.In this lesson, we'll learn a few basic principles of stratigraphic succession and see whether we can find relative dates for those strange strata we found in the Grand Canyon.In order to establish relative dates, geologists must make an initial assumption about the way rock strata are formed. sediments, which are deposited and compacted in one place over time.Since we assume all the layers were originally horizontal, then anything that made them not horizontal had to have happened after the fact.

Numerical dating determines the actual ages of rocks through the study of radioactive decay.Let's say we find out, through numerical dating, that the rock layer shown above is 70 million years old.
