The simplest and most intuitive way of dating geological features is to look at the relationships between them. For example: Did rock layer A form before or after rock layer B? Did trilobites live before or after the dinosaurs? Relative age dating has to do with determining.

September 30, by Beth Geiger. For example, based on the primate fossil record, scientists know that living primates evolved from Relative dating to determine the age of rocks and fossils . Relative dating is the science of determining the relative order of past events i.
Ina young doctor named Nicholas Steno was invited to dissect the head of an enormous great white shark that had been caught by local fisherman near Florence, Italy. For example, the principle of superposition states that sedimentary layers are relationships outlined above, determine the relative ages of these three rock.
Relative age dating also means paying attention to crosscutting relationships. Say for example that a volcanic dike, or a fault, cuts across.
