Can relative dating always be used Afult video chat
As time passes, the organic components of bone (mostly fat) are lost primarily through bacterial action.Since these components contain nitrogen, there is a progressive loss of that element.The skull and jaw clearly were not from the same time period.The jaw was likely to have come from a modern young adult orangutan.If not, then at least one of them must be physically out of context.it had an ape-like jaw and was found in association with the bones of extinct animals, this "Piltdown Man" was also believed to be a very ancient human.However, forces that can disturb relative dating or at least make it more challenging include multiple geological processes occurring over a short period of time.If the layers you're examining are very small, it can be hard to determine for sure which occurred first.
As a result, it was difficult to chronologically compare fossils from different parts of the world.
In terms of paleontology, if an earthquake occurs and moves a fossil to another layer of the earth, one would think that fossil is older or younger than it is. By burying our dead, we impose them into geologic layers that we, ourselves, did not actually live in.
Erosion could also take a mineral or fossil out of position and place it in another layer, thus causing humans to incorrectly assume an older or different age.
Relative dating is the process of determining the age of an artifact, a layer of rock, a fossil, or something else by using the position of that item in relation to other surrounding rock layers and items.
(Remember, we are only able to determine whether something is older or younger compared to something else.) See this link for a thorough review of how relative dating is done.
