The principle of superposition states that in an undisturbed sequence of sedimentary rock layers, the oldest layer is at the bottom and the youngest layer is at the top. This principle is helpful in determining the age of the earth because scientists can use the relative ages of rock layers to establish a timeline of events and estimate the age of the earth based on the amount of time it would take for these layers to form.
