C-12 is stable, meaning it does not decay into other elements over time. It is formed when cosmic radiation strikes N-14 (Nitrogen), converting it into C-14, and it decays back into N-14, with a half-life of 5730 years, meaning that for any sample of C-14, half of it will decay back into N-14 every 5730 years.Carbon-14 is used to date dead plants and animals, because plants and animals incorporate C-14 into their bodies by eating, drinking, and breathing in an environment containing C-14.

Carbon 14 dating denotes amount

Carbon-14 dating is based on the ratio of available Carbon-14 versus what is actually found in living systems.

If this ratio is inconsistent, Carbon-14 dating cannot be accurate.

Let's say that 1/4th of the water evaporates each day, so that at the end of day 3, someone notes that there is 1/4th of the water remaining, where 3/4ths have evaporated.

Now take the same one-pint container and pour it evenly into four graduated flasks, each one initially containing 1/4th of a pint.

It is impossible to determine whether it has always been increasing (as argued by some creationists) or whether it has undergone cycles of increase and decrease (as argued by other creationists and evolutionary scientists).

But one thing is certain: there is no reason to believe that the C-14: C-12 proportion has been constant throughout time, and good reason to believe it has been different, and often lower, in the past than it is today.Carbon-14 dating is a radiometric dating technique used to deduce the approximate age of organic remains by measuring the quantity of C-14 isotopes in the sample and comparing them with current atmospheric levels.C-12 and C-14 are two different isotopes of carbon.This dilution artificially skews a measurement if we use today's ratios.An example follows: We have a one-pint container and pour its contents into a graduated flask, then come back each day to check on the water's evaporation.The rate of C-14 production today is 18% higher than the rate of decay (Whitelaw).
