Where did the air get its C? But if there can be small fluctuations in the amount of the C produced in the atmosphere day by day, then there could have been greater fluctuations in Earth's history.

The isochron technique involves collecting a number of rock samples from different parts of the rock unit being dated.

Again, the stories are evaluated according to their own success in agreeing with the existing long ages belief system. When a plant or animal organism dies, however, the exchange of radiocarbon from the atmosphere and the biosphere stops, and the amount of radiocarbon gradually decreases, with a half-life of approximately years.
