A geologist examining a road cut at this location would recognize that Layer A is younger than Layer B. This conclusion is made through the principle of superposition .
The principle of superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest layers are at the top. By observing the road cut, the geologist can see that Layer B is located below Layer A. This indicates that Layer B was deposited before Layer A, making Layer B older. Therefore, the conclusion can be made that Layer A is younger than Layer B.
