Detailed explanation-1: -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-2: -The principle of superposition states that in an undisturbed rock sequence, the oldest rocks are at the bottom and each successive layer is younger than the layer beneath.

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: -The superposition principle states that when two or more waves overlap in space, the resultant disturbance is equal to the algebraic sum of the individual disturbances. (This is sometimes violated for large disturbances; see below Nonlinear interactions.)

Detailed explanation-5: -From his work in the mountains of western Italy, Steno realized that the principle of superposition in stratified (layered) rocks was the key to linking time to rocks. In short, each layer of sedimentary rock (also called a “bed”) is older than the one above it and younger than the one below it.
