Answer:
B. LZAQD
A. Younger than A but older than Q
Explanation:
To solve this problem, we simply apply the stratigraphic laws which are the law of superposition and principle of cross cutting.
- According to the law of superposition, in an undeformed sequence of strata, the oldest layer is always at the bottom and the youngest on top.
- In this case, we have a little disturbance but it did not affect much of the original bedding.
- So, the rock ages from L to Z to A to Q and D. L is the oldest and D is the youngest.
According to the principle of cross-cutting "features that cuts through a rock are younger than the layers they cut through". In this problem, the fault cuts through layers LZ and A which suggests that these layers are older than the faulting event. Layer Q is unaffected by the faulting so, the fault is older than the layer.
