Quizplus · Accepted Answer

Stratigraphy is the study of layers of rock, particularly sedimentary rock, and the relationships among them. Geologists can use the succession of different rock layers to determine the relative ages of fossils found within them, which has helped to divide the geologic time scale into distinct eras, periods, and epochs.
