When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen. This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.The period of time that it takes for half of a sample to decay is called a "half-life." Radiocarbon oxidizes (that is, it combines with oxygen) and enters the biosphere through natural processes like breathing and eating.Plants and animals naturally incorporate both the abundant C-12 isotope and the much rarer radiocarbon isotope into their tissues in about the same proportions as the two occur in the atmosphere during their lifetimes.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.

Dating is not necessary to demonstrate that evolution is a fact.

You may find it useful for the clear definitions, and for excellent links on a variety of topic.

This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.

A few examples of such lies are presented at the very bottom of this page.

For each dating or chronological method there is a link in the box at right to take you to that section of this page.
