As these organisms die they are deposited on the surface along with all other sediments. If conditions are right the remains of the dying organisms can then be preserved as fossils within the rock that formed from sediments that covered the remains. Since, all sedimentary rock is formed through the gradual accumulation of sediment at the surface over time, and since the principle of superposition tells us that newer sediment is deposited on top of older sediment, the same must also be true for fossils contained within the sediment.

Although this principle is generally applied to relative dating it is also the basis for evolution. Principles of Relative The Principle of Superposition tells us that deeper layers of rock are older than shallower layers Relative dating utilizes six fundamental principles to determine the relative age of a formation or event.

This follows due to the fact that sedimentary rock is produced from the gradual accumulation of sediment on the surface. Therefore newer sediment is continually deposited on top of previously deposited or older sediment. In other words, as sediment fills a depositional basins we would expect the upper most surface of the sediment to be parallel to the horizon.

Relative dating

Subsequent layers would follow the same pattern. As sediment weathers and erodes from its source, and as long as it is does not encounter any physical barriers to its movement, the sediment will be deposited in all directions until it thins or fades into a different sediment type.

For purposes of relative dating this principle is used to identify faults and erosional features within the rock record. The principle of cross-cutting states that any geologic feature that crosses other layers or rock must be younger then the material it cuts across.
