Stratigraphy is a branch of geology that deals with the study of rock layers and their sequences. By analyzing the layers of rock and fossils in them, scientists can determine the relative age of the earth's surface. This method helps scientists to understand the geological history of the earth and to determine when various geological events took place, such as the formation of mountains or the extinction of certain species.
