Relative dating is the science of determining the relative order of past events i. 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 early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.

Geologic Time Scale | Earth Science

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating , to give rocks an actual date , or date range, in number of years. This is different to relative dating , which only puts geological events in time order. Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. Later, scientists used absolute dating to determine the actual number of years ago that events happened. The fossils in the strata are used to determine relative dates, the simpler the fossil the older the fossil. Strata are dated based on the fossils found in them.
