Answer:
Faulting created the differences in layers
Layers 2 and 9 are of the same age
Explanation:
The principle we use to solve this problem is the principle of cross-cutting and fossil and fauna succession.
The principle of cross-cutting entails that faults are younger than the rocks they cut through.
Principle of fossil and fauna succession suggests that fossils succeed one another in a systematic manner.
It is true that the normal fault cause an extension of this topography and created the differences in layers that originally was in place.
Also, layers 2 and 9 have the same fossil types and are of the same age.
