How does carbon dating rocks work

More information
Three types of carbon occur naturally in living material: C12, C13 and C Carbon14 C14 is unstable and present in a very small percentage relative to the other components. The rate of decay or half-life of C14 was proven linear, allowing scientists to determine the approximate date of the expiration of a life form based on the amount of C14 remaining in the fossil. This dating can be used on once-living items and can provide information on related spaces. For example, an age can be estimated for a strata of rock based on the age of the skeletons it holds.

How Carbon-14 Dating Works

Pollen dating, is one of the lesser utilized methods archaeologists have to determine a relative chronology or timeframe for a certain event. Pollen dating can determine a relative time frame far earlier than radiocarbon dating is able. Although, because of influences such as pollen transportation by wind for thousands of miles and the abundance of certain kinds of pollen, radiocarbon dating is necessary to give absolute dates. Pollen dating is done by comparing the pollen zones in different rock layers or strata, comparing older, deeper layers to newer ones on top. The pollen zone is the particular time frame where specific species of plants release more pollen into the air than others.

When the radiation of the sun hits the atmosphere of the earth, this energy converts about 21 pounds of nitrogen into radioactive carbon Living organisms are constantly taking Carbon 14 into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new carbon 14, and the old carbon 14 starts to decay back into Nitrogen 14 by emitting beta particles.
