Which describes the difference between the law of inclusion and the law of cross-cutting in relative dating of rocks and fossils
The law of inclusion states that, in a sequence of undisturbed sedimentary rocks, any rock fragment included within another rock must be older than the rock that contains it. This is because the rock containing the fragment must have formed after the fragment itself was already present.
On the other hand, the law of cross-cutting relationships states that any geological feature that cuts across another feature must be younger than the feature it cuts across. For example, if a fault cuts across a layer of sedimentary rock, the fault must have formed after the layer of rock was already deposited.
Overall, the main difference between the two laws is that the law of inclusion focuses on the relationships between individual rock fragments within a sequence of rocks, while the law of cross-cutting relationships looks at the relationships between different geological features.
