b. The fault is younger than the layers it cuts through, but older than the layers above it.
Explanation:
Since the fault cuts through the lower rock layers and terminates against the ones above it, we can conclude that the fault is younger than the layers it cut through but older than the layers above it.
We know this based on the principle of cross-cutting.
The principle of cross-cutting relationship suggests that "a fault and an intrusion is younger than the rocks they cut through".
- This principle is very important in determining the relative age of sedimentary strata.
- The rock units through which a fault permeates must have been there before the fault formed. So they are older.
- If the overlying layer above the fault is not affected then it is younger than the faulting event

Answer:
Photosynthetic organisms was the reason of these atmospheric changes.
Explanation:
The plant which is discovered by the scientists that is apparently devoid of life but has ice caps located at the poles which reveals that planet's atmospheric O₂ levels sharply increased about 1,000,000 years ago was due to evolution of photosynthetic organisms like cyanobacteria etc which went extinct and then O₂ levels dropped quickly 50,000 years ago. So photosynthetic organisms was the reason of these atmospheric changes.
