Relative dating is the science of determining the relative order of past events without necessarily determining their absolute age (i.e. estimated age). In geology, rock or superficial deposits, fossils and lithologies can be used to dating, archaeologists and geologists used relative dating to determine ages of materials. As a member, you'll also get unlimited access to over 75, lessons in math, English, science, history, and more.
