Relative dating is the science of determining the relative order of past events without necessarily determining their absolute age, (ie estimated age) in geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another prior to the discovery of radiometric dating in the. Using the tennants of relative dating, smith noted the geographic extent of various rocks and fossils throughout england and was able to create a map that illustrated their distribution smith realized that certain rock layers contained certain types of fossils the older the rock, the more primitive the fossil. Early geologists had no way to determine the absolute age of a geological material if they didn't see it form, they couldn't know if a rock was one hundred years or 100 million years old what they could do was determine the ages of materials relative to each other using sensible principles they could say.
