this diagram shows rock layers x, y, and z in a fault zone. this diagram also shows an intrusion, i. which conclusion is most likely correct? a layer y is younger than intrusion i. b layer y and the fault formed at the same time. c layer z is older than layer y. d layer z and intrusion i formed at the same time.

this diagram shows rock layers x, y, and z in a fault zone. this diagram also shows an intrusion, i. which conclusion is most likely correct? a layer y is younger than intrusion i. b layer y and the fault formed at the same time. c layer z is older than layer y. d layer z and intrusion i formed at the same time.

Answer

Brief Explanations:

In geology, the principle of superposition states that in undisturbed sedimentary rock layers, the oldest layers are at the bottom and the youngest are at the top. Also, an intrusion is younger than the rock layers it cuts through. Here, intrusion I cuts through layer Y, so layer Y is older than intrusion I. The fault cuts through layer Y, so they didn't form at the same time. Layer Z is above layer Y, so layer Z is younger than layer Y. Since intrusion I cuts through layer Z, they didn't form at the same time.

Answer:

C. Layer Z is older than layer Y.
