Basic geologic principle that originally horizontal layers have the oldest layers on the bottom and youngest layers on the top of a sequence, i.e., whatever is on the top is younger and vice versa.

(geology) the deposition of one geological stratum on another

(geology) the principle that in a series of stratified sedimentary rocks the lowest stratum is the oldest

The principle by which the displacements from different waves traveling in the same medium add up. Superposition is the basis for interference.

The adding together of two waves to form a third wave. This wave will no longer exist as the two original waves continue on their way. Image of superposition of two waves.

A quantum mechanical phenomena in which an object exists in more than one state simultaneously. [NTN

The act of superposing, or the state of being superposed; as, the superposition of rocks; the superposition of one plane figure on another, in geometry.

(geometry) the placement of one object ideally in the position of another one in order to show that the two coincide

the placement of one thing on top of another

A hybrid structure is one that is derived from two different parent structures. This structure is not exactly like either of the two structures is came from. Instead, it is a combination of both structures.

a state, where two (or more) potentials are present but have not manifested themselves

An important property of sound fields in which, what happens at a point in space is the vector sum of all separate events. It means that one can analyze individual components, e.g. direct and reflected sounds, and then mathematically add them together to determine the final result, exactly as happens in the physical world.

In perception, a monocular cue for depth. If an object has contours that cut through those of another, obstructing the other object?s view, the overlapping object is perceived as being nearer. See also distance cues, linear perceptive, relative height, relative size.
