Final answer:

The oldest rocks in the Grand Canyon are located at the bottom due to the principle of superposition.


Explanation:

The oldest rocks in the Grand Canyon are found at the bottom. The principle of superposition states that in an undisturbed sequence of rock layers, the oldest rocks will be at the bottom and the youngest at the top. This is evident in the stratigraphy of the Grand Canyon where the oldest sedimentary formations and igneous rocks are indeed found at the base.
