Detailed explanation-1: -The Law of Superposition, which states that in an undisturbed horizontal sequence of rocks, the oldest rock layers will be on the bottom, with successively younger rocks on top of these, helps geologists correlate rock layers around the world.
Detailed explanation-2: -The principle of superposition states that in an undeformed sequence of sedimentary rocks, each layer of rock is older than the one above it and younger than the one below it (Figures 1 and 2). Accordingly, the oldest rocks in a sequence are at the bottom and the youngest rocks are at the top.
Detailed explanation-3: -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-4: -Superposition: The most basic concept used in relative dating is the law of superposition. Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it.
Detailed explanation-5: -The law of superposition essentially says that in a sequence of sedimentary rocks or in layers of soil, the oldest layers will be at the bottom and the newest layers will be at the top. Using this law, scientists can determine the relative age of fossils based on the layers of sediment in which they’re found.
