Why do we use carbon 14 for carbon dating updating 2 wire outlets
Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.
However, the decaying carbon-14 is constantly being replaced as the plant or animal consumes more carbon-14 from the air or through its food.
Carbon-14 is created from nitrogen-14 in the upper atmosphere of the earth.
Radiation from the sun collides with atoms in the atmosphere.
By comparing the ratio of carbon-14 to carbon-12 in an artifact to the ratio of carbon-14 to carbon-12 in living organisms scientists can determine the age of an artifact.
If you wanted to date a fossil, first you would determine the percent carbon-14 it contained compared to a living sample.
