Relative dating



























Geologists routinely work in millions and billions of years , so normal calendars and methods of representing spans of time don't always work very well. Fortunately, being as clever as they are, geologists have managed to come up with other ways. Ever since the first human looked at a piece of the earth and wondered about it, we have been assigning a relative order to the events which have taken place.

A few days ago, I wrote a post about the basins of the Moon -- a result of a trip down a rabbit hole of book research. In the science of geology, there are two main ways we use to describe how old a thing is or how long ago an event took place. There are absolute ages and there are relative ages. People love absolute ages.

An absolute age is one determined usually by mass-spectrometry where an isotope is measured and then an age can be calculated a very very basic explanation. So in the end you can say this fossil is 50 thousand years old always with an associated uncertainty. We can absolute date materials but it will always have an uncertainty range, we can never know the age with infinite precision. Relative dating is like looking at a multi-layered cake. The base layer must come first, then the second and then the third.

  1. Geologists often need to know the age of material that they find. This is different to relative dating, which only puts geological events in time.
