A method of determining the age of a fossil by comparing its placement with that of fossils in other layers of rock. 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.

Here we come to the question of how accurate the dates are that we currently have regarding the history of the human race and our planet. Even though more than one method of verification is used in most cases, the lack of an accurate method to date non-organic materials lends a certain degree of uncertainty to the accepted history of our planet.
It is also important not to forget that throughout the history of humankind any discovery that shakes the status quo is always under attack until it becomes established, and we are in an era where many of the things that we once considered certain will become errors of our past.

Radiometric dating is the key to developing and understanding an absolute time scale of Earth and its geologic ages. When geological events, rock formations, and individual species can be placed accurately in time, it becomes possible to understand their relationships to each other and to events and circumstances present today. May 18, Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.
