Radiocarbon dating definition for kids 13 sexchat

Carbon combines with other elements in complex ways to form the molecules that make up our bodies.

Thus, as living things take in carbon, they inevitably will take up a small amount of radioactive carbon into their bodies.

When these lifeforms die, they stop taking in new carbon.

The carbon in their bodies at the time of their death will remain in their bodies until they decompose, or if they become fossilized, then forever. This allows scientists to look at the amount of decay in a fossil’s radioactive carbon and determine a relative date.

Radiocarbon dating is only effective for objects and fossils that are less than 50,000 years old.
