the cross section below shows rock layers a, b, c, d, and fault f. the rock layers have not been overturned. which sequence places the rock layers and fault in order from oldest to youngest? a) d→c→b→a→f b) a→b→c→d→f c) f→d→c→b→a d) f→a→b→c→d
Answer
Brief Explanations:
According to the principle of superposition in geology, in an undisturbed sequence of sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top. Also, a fault is younger than the rock layers it cuts through. Here, layer D is at the bottom, followed by C, B, A, and the fault F cuts through all the layers, so it is the youngest.
Answer:
A. D → C → B → A → F
