Explain the process of carbon dating
It takes about 5,730 years for half of a sample of radiocarbon to decay back into nitrogen.It takes another 5,730 for half of the remainder to decay, and then another 5,730 for half of what's left then to decay and so on.The New Zealand curve is representative for the Southern Hemisphere, the Austrian curve is representative for the Northern Hemisphere. This makes it possible to tell the age of substances that contain carbon. Dates obtained are usually written as before present ('present' is 1950).
C and counting the amount of each) allows one to date the death of the once-living things.C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.
