Free carbon, including the carbon produced in this reaction, can react to form carbon dioxide, a component of air. Atmospheric carbon dioxide, CO2, has a steady-state concentration of about one atom of carbon per every atoms of carbon

Carbon atoms come in many forms (called isotopes). The most stable form is Carbon Carbon is a unstable form of carbon. Carbon is replenished in the upper atmosphere when cosmic rays bombard Nitrogen atoms and converts them to Carbon So a small percentage of carbon atoms in the CO2 in the atmosphere are Carbon atoms.
The ratio of normal carbon (carbon) to carbon in the air and in all living things at any given time is nearly constant. Maybe one in a trillion carbon atoms are carbon The carbon atoms are always decaying, but they are being replaced by new carbon atoms at a constant rate.
However, a tiny percentage of this carbon is radioactive! Measuring the quantity of this radioactive carbon in organic matter allows us to determine its age; the method of doing so is called radioactive carbon dating or, simply, carbon dating.
Carbon dating only works on relatively recent organic material (better when it's been cross-checked with tree ring data; there are correction tables) Fossils are dated by the rock strata they are found in, and isotopic dating can be used in a similar way to carbon dating.
Carbon dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50, years old. It is used in dating things such as bone, cloth, wood and plant fibers that were created in the relatively recent past by human activities. how does carbon dating work yahoo answers.

Carbon Dating - The Controversy Carbon dating is controversial for a couple of reasons. First of all, it's predicated upon a set of questionable assumptions. We have to assume, for example, that the rate of decay that is, a 5, year half-life has remained constant throughout the unobservable past. Carbon dating and other forms of radiometric dating are incredibly accurate because an unstable molecule degrades at a specific half-life regardless of other factors. Carbon is good for a few thousand years but there are a lot of other elements that can be used too.
Amounts of Carbon are not the same as they were before the flood. Now things born are not born with the right amount of Carbon, which its seem older then it really is. Also other things may change the amount of Carbon the fossil or rock has. How Does Carbon Dating Work - Radiocarbon That is why radiocarbon dating cannot give mil lions of years. In fact, if a sample contains 14 C, it is good evidence that it is not millions of years old. What about carbon dating? - Creation Radiocarbon dating has also been used to date the extinction of the woolly mammoth and contributed to the.
