We will deal with carbon dating first and then with the other dating methods.

Carbon has unique properties that are essential for life on Earth.

Radiocarbon dating works because an isotope of carbon, C, is constantly formed in the atmosphere by interaction of carbon isotopes with solar radiation and free neutrons.

Living organisms absorb carbon (for example, we breathe it in).

The physics of decay and origin of carbon 14 for the radiocarbon dating1: Formation of Carbon-14.2: Decay of Carbon-14.3: The “equal” equation is for living organisms, and the unequal one is for non-living ones, in which the C-14 then decays (hence the 2).

From: Wikimedia Commons We can indirectly date glacial sediments by looking at the organic materials above and below glacial sediments. Marine geological constraints for the grounding-line position of the Antarctic Ice Sheet on the southern Weddell Sea shelf at the Last Glacial Maximum.

, and is so rare that only one-in-a-trillion carbon atoms are carbon-14.

But there is another form of carbon that, while not at all abundant, is definitely worth talking about.

"Every year the trees in our forests show the swing of Time's pendulum and put down a mark.

They are chronographs, recording clocks, by which the succeeding seasons are set down through definite imprints," he wrote in the pages of National Geographic.

Radiocarbon dating provides the age of organic remains that overly glacial sediments.

It was one of the earliest techniques to be developed, during the 1940s.
