Realative dating age of rocks Gratis milf chat
This theory held that the past was the key to the future and that processes that formed the layers were the very slow processes that we see forming layers at the bottom of the ocean today. Until Lyell successfully convinced scientists that uniformitarianism was the correct theory, it was believed that the worldwide flood and other catastrophic events were primarily responsible for the formation of the geologic layers and that they didn’t represent long ages.Later, when radiometric absolute dating methods were developed, they still were not applicable to sedimentary layers. ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.This technique does not give specific ages to items.
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. Using this principle we can than assume that sedimentary layers which have been deformed/folded must have been deformed after all affected layers have been deposited.
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.
Using this principle any fault or igneous intrusion must be younger than all material it or layers it crosses.
The relative dating methods themselves are generally sound when used with good assumptions.
However, when scientists apply relative dating to a preconceived uniformitarianism model, the dating methods are only as good as the model.
