By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata this is called relative dating relative dating tells scientists if a rock layer is older or younger than another this would also mean that fossils found in the deepest layer of rocks in an area would represent the. Relative age dating has given us the names we use for the major and minor geologic time periods we use to split up the history of earth and all the other is based on relative time units in which global reference points at boundary stratotypes define the limits of the main formalized units, such as permian.

This is similar to what geologists do to determine age relative dating is determining whether an object is older or younger than other objects this means that you know which events came first, but not the exact time when they happened.
