B) the sandstone must be older, according to the principle of superposition
C) the granite must be older, according to the principle of components
D) their relative ages cannot be determined from the information given

Question

Quizplus · Accepted Answer

The principle of superposition only states that in an undisturbed sequence of sedimentary rocks, the oldest layer is at the bottom and the youngest layer is at the top. However, it does not provide any information about the relative ages of different types of rocks. Similarly, the principle of components states that a rock is older than any pebbles or fragments it contains, but it also does not help to determine the relative ages of granite and sandstone. Therefore, without additional information or context, their relative ages cannot be determined from the given information alone.
