Answer:
A fault breaks through sedimentary layers.
Explanation:
The principle of cross-cutting relationships is useful in determining the relative age of rocks when fault breaks through sedimentary layers.
- This principle suggests that faults and fractures are younger than the layers they cut through.
- When a fault cuts through a sequence, its is younger than the faulting event.
- Therefore, we can use the relationship to determine the relative age of the sequence.
