Question

James looked at a picture of rock layers while studying how scientists determine the ages of rocks. He looked at the variety of layers and understood that the law of superposition indicated something about the rock layer ages. What does the law of superposition indicate?

Answer 1

Step-by-step explanation:

The law of superposition is a basic principle of geology that states that in an undisturbed sequence of sedimentary rocks, the oldest layer is at the bottom and the youngest layer is at the top. In other words, younger layers are deposited on top of older layers, and each layer is younger than the one beneath it. This principle is important for determining the relative ages of rock layers and the order in which they were formed. By examining the position of rock layers, geologists can infer the relative ages of the rocks and make conclusions about the geological history of the area.
