The material is older and the object composed of it is less old if we elaborate the law of superposition in detail it means that the oldest strata lie at the bottom and the newer strata at the top. Superposition is the name for the observation that given a stack of layers or beds of sedimentary rocks older beds are found below younger beds as long as there has been no disturbance of the.
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.
Law of superposition definition science. So this law is based on the common sense of proof. According to the law of superposition nothing can be older than the material composing it. Law of superposition definition a basic law of geochronology stating that in any undisturbed sequence of rocks deposited in layers the youngest layer is on top and the oldest on bottom each layer being younger than the one beneath it and older than the one above it.
On occasion however deformation may have caused the rocks of the crust to tilt perhaps to the point of overturning them. Law of superposition definition is a law in geology. The law of superposition is an axiom that forms one of the bases of the sciences of geology archaeology and other fields pertaining to geological stratigraphy.
This law has a proven record of being able to accurately determine the relative ages of the different layers of soil. The law of superposition is one of the most fundamental principles of stratigraphy the branch of archeology which studies the geological layers of the earth and soil. Where there has been no subsequent disturbance sedimentary strata were deposited in ascending order with younger beds successively overlying older beds.
