The principle of superposition which states that in undeformed rocks,the younger rocks will be on top of older rocks,is particularly important because ________.
A)it supports the laws of gravity which indicate that rocks must be deposited on something that already exists
B)it showed that the interior of the earth is not growing outward
C)it provided an order for assembling the relative ages of various rock layers
D)it proved that life evolved by putting fossils in a logical order

The principle of superposition is important because it provides a way to determine the relative ages of rock layers. The younger rocks are always on top of the older rocks, so if you see a layer of rock on top of another layer, you can assume that the layer on top is younger. This allows geologists to assemble the relative ages of different rock layers and create a geological history of an area.
