A- Law of Superposition
The Law of Superposition is a key concept in geology that is used to determine the relative ages of sedimentary rock layers. According to this law, in any undisturbed sequence of rocks deposited in layers, the youngest layer is on top and the oldest on the bottom, each layer being younger than the one beneath it and older than the one above it. This principle is what would describe a layer of the Grand Canyon as being older than the layer above it.
