Fault B cuts across several layers of rock. Which conclusion can be made? (1 point)
Fault B is younger than layer D base on the law of inclusion
Fault B is older than layer D based on the law of crosscutting
Fault B is younger than layer C based on the law of crosscutting
Fault B is older than layer C based on the law on inclusion
Fault B is older than layer D based on the law of crosscutting.
Based on the information provided, the conclusion that can be made is: Fault B is older than layer D based on the law of crosscutting.
To determine the conclusion using the principles of relative dating, we need to understand the laws of inclusion and cross-cutting relationships.
The Law of Inclusion states that in an undisturbed sequence of layers, each layer is younger than the one beneath it. This means that if Fault B cuts across several layers of rock, it must be younger than those layers.
On the other hand, the Law of Cross-Cutting Relationships states that any feature that cuts across a rock layer must be younger than the rock layer it cuts through. This means that Fault B, as it cuts across the layers, must be younger than those layers it is cutting across.
Comparing the given conclusions:
1. Fault B is younger than layer D based on the law of inclusion: This conclusion is incorrect because layer D is not mentioned to be above or below Fault B, making it impossible to determine the relative ages based solely on the law of inclusion.
2. Fault B is older than layer D based on the law of cross-cutting: This conclusion is correct because the Law of Cross-Cutting Relationships indicates that Fault B must be younger than layer D if it cuts across it.
3. Fault B is younger than layer C based on the law of cross-cutting: This conclusion is incorrect because based on the Law of Cross-Cutting Relationships, Fault B must be younger than layer C, not older.
4. Fault B is older than layer C based on the law of inclusion: This conclusion is incorrect because the law of inclusion only applies to layers stacked on top of each other, and it does not apply to features like faults cutting across layers.
Therefore, the correct conclusion is: Fault B is older than layer D based on the law of cross-cutting.
