Question

what is the law of superposition

Answer 1

The law of superposition is a fundamental principle in geology and archaeology that states that in any sequence of undisturbed sedimentary rocks or archaeological strata, the youngest layers are found on top, while the oldest layers are found at the bottom. This principle helps scientists determine the relative ages of rocks and artifacts. It is based on the idea that in undisturbed layers, the deposition of new sediments or archaeological material occurs on top of older layers over time. By studying the order of layers, scientists can establish a relative chronology of events or determine the relative age of fossils and artifacts.
