Carbon dating method reliable Totalyfreechatlines com
Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere; the neutrons required for this reaction are produced by cosmic rays interacting with the atmosphere.
Radiocarbon present in molecules of atmospheric carbon dioxide enters the biological carbon cycle: it is absorbed from the air by green plants and then passed on to animals through the food chain.
Carbon-14 has a half-life of 5,730 ± 40 years—, half the amount of the radioisotope present at any given time will undergo spontaneous disintegration during the succeeding 5,730 years. It has proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old.
Here we come to the question of how accurate the dates are that we currently have regarding the history of the human race and our planet.
The experts will tell you ‘yes’ within certain limits.
However, results have a tendency to support the person paying.
That said, when used with integrity, it can be a lot, lot better than paleography.
Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.
