This photograph shows the law of superposition at work. What is the law of superposition? * 1 point A fault or intrusion of rock younger than the rock it cuts through. In undisturbed rock layers, the older rocks are on the bottom and the younger rocks are on the top.
The law of superposition states that in an undisturbed sequence of sedimentary rock layers, each layer is younger than the one beneath it and older than the one above it. This means that the oldest rocks are found at the bottom, while the youngest rocks are found at the top.
