Detailed explanation-1: -Scientists use a basic principle called the Law of Superposition to determine the relative age of a layer of sedimentary rock. *The Law of Superposition is that an undeformed sedimentary rock layer is older than the layers above it and younger than the layers below it.
Detailed explanation-2: -law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
Detailed explanation-3: -Superposition. Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.
