Detailed explanation-1: -Correct! Superposition states that in an undisturbed sequence of rock strata, the layer underneath must already exist before another layer can be deposited on top of it therefore is older.

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: -The law of superposition is one of the principles of geology scientists use to determine the relative ages of rock strata, or layers. This principle states that layers of rock are superimposed, or laid down one on top of another. The oldest rock strata will be on the bottom and the youngest at the top.

Detailed explanation-4: -Relative chronology is based on a classic geological principle, known as the Law of Superposition. This law holds that, under normal circumstances, deeper layers of soil, sediment, or rock are older than those above them.
