6. Scientists can determine the age of ancient objects by a method called . Radiocarbon dating The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, carbon-14, with a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates carbon-14 through food chains. When a plant or animal dies, it stops replacing its carbon and the amount of carbon- 14 begins to decrease through radioactive decay.
