What does the law of superposition? 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.
What is the law of superposition and who proposed it? The Law of Superposition is a geologic principle, first observed and named by Friedrich von Schiller in 1785. It states that rock layers are always in contact with younger rock layers (but not with older ones), because younger rock layers are younger and therefore more closely related in time to the older layers.
What are some examples law of superposition? An example would be that the silt back-fill of an underground drain would form some time after the ground immediately above it. Other examples of non vertical superposition would be modifications to standing structures such as the creation of new doors and windows in a wall.
