Title: Relative Geologic Dating.
Caption: This animation depicts many of the important principles of relative dating. It begins with the deposition of sedimentary layers in an aqueous environment. It then shows the formation of faults and subsequent movement along them, the intrusion of a batholith, and the creation of dikes and sills.
