Principle of superposition relative dating
The principle of superposition states that every charge in space creates an electric field at point independent of the presence of other charges in that medium.
The resultant electric field is a vector sum of the electric field due to individual charges.
The relationship is interference is the addition of two or more wave pattern and the principle of superposition is the displacement of any point due to the superposition of wave system equal to the sum of the displacements of the individual waves at that point.
Superposition is the principle that states that, in undisturbed strata, newer layers will be deposited over older layers; thus, in a core sample, those samples of earth and rock nearest the surface will be newer in age than those beneath them.
The electrostatic forces obey principle of superposition because these forces are independent of each other.
It means that if an electric force is applying on a charge than this will not effected by any other field.
One example of this is a xenolith, which is a fragment of country rock that fell into passing magma as a result of stoping.
Relative age is determined by comparison to other fossils by referring to geologic timescale.
Sometimes magma pushes, or intrudes, into cracks in existing rocks. The Law of Original Horizontality was first proposed by Danish geological pioneer Nicholas Steno in the 17th century.
The principle of cross-cutting relationships states that an igneous intrusion is always younger than the rock it cuts across. Examine the igneous intrusion and the surrounding rock. 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. The law states that layers of sediment were originally deposited horizontally under the action of gravity.
Scientists use a basic principle called the Law of Superposition to determine the relative age of a layer of sedimentary rock.
