Carbon dating limit

When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.

Scientists use a technique called radiometric dating to estimate the ages of rocks, fossils, and the earth.

It is naturally unstable and so it will spontaneously decay back into N-14 after a period of time.

C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.

C-14 is produced in the upper atmosphere when nitrogen-14 (N-14) is altered through the effects of cosmic radiation bombardment (a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope).

With our focus on one particular form of radiometric dating—carbon dating—we will see that carbon dating strongly supports a young earth.

Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.

The amount of carbon-14 in the air has stayed the same for thousands of years.
