Quizplus · Accepted Answer

The principle of superposition states that in an undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom and the youngest layers are at the top. However, this principle cannot be used to determine the relative ages of granite and sandstone as they are both igneous and metamorphic rocks, and not sedimentary rocks. The principle of components also cannot be used as it applies to the relative ages of minerals within a rock, not to the ages of entire rocks. Therefore, without additional information or context, we cannot determine the relative ages of the granite and sandstone.
