Superposition
01
the act or process of placing one object or entity directly above or on top of another
02
(geometry) the placement of one object ideally in the position of another one in order to show that the two coincide
03
a principle in geology stating that in a sequence of undisturbed sedimentary rock layers, the youngest rocks are at the top, and the oldest rocks are at the bottom, helping determine the relative ages of geological formations
04
(geology) the deposition of one geological stratum on another
Example
Superposition is a key tool for correlating rock formations across different locations and regions.
The principle of superposition assists geologists in deciphering the chronological order of rock layers in a given geological formation.
The concept of superposition is fundamental to constructing geological timelines and understanding Earth's history.
In an undisturbed sequence of rocks, the lower layers, according to the principle of superposition, are older than the layers above.
By studying superposition, scientists can infer the relative ages of fossils found in different sedimentary layers.
