premise: The first and most simple technique is the law of superposition, which simply states that in a sequence of sedimentary rock, the rocks in the upper layers of sediment are younger than the rocks at the bottom.
hypothesis: The law of superposition is best described by: in undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
