This photograph shows the law of superposition at work. What is the law of superposition?

Answer 1

The law of superposition is a fundamental principle in geology and archaeology that states that in an undisturbed sequence of layers or strata, the oldest layer is located at the bottom, while the youngest layer is found on top. This principle is based on the understanding that sedimentary rocks and archaeological materials are typically deposited or accumulated in chronological order over time. By examining the relative positions of different layers or artifacts, scientists can deduce the relative ages of the materials and establish a timeline of events or geological history.
