GEOLOGY

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: -The law of superposition is the principle that states that younger rocks lie above older rocks if the layers have not been disturbed.

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: -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-5: -Law of Superposition The relative ages of rocks are important for understanding Earth’s history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition.
