Question

Which conclusion can be made a fault cuts across several layers of rock

Answer 1

When a fault cuts across several layers of rock, it indicates that the fault is younger than the rock layers it disrupts. This conclusion is based on the principle of geological superposition, which states that in an undeformed sequence of sedimentary rocks, the oldest layers are at the bottom, while the younger layers are at the top. Therefore, if a fault intersects multiple layers, the fault itself must have formed after those layers were deposited and solidified. Additionally, the characteristics and displacement of the fault can provide insights into the geological history and tectonic processes that have affected the area.
