Artifact : an object formed by humans. Carbon : a chemical element important to life on Earth; it is one of the most abundant elements in the universe. Carbon isotopes : atoms of carbon that have different numbers of neutrons; isotopes are sometimes used to determine the diet of mammal herbivores by analyzing the carbon in fossilized teeth. DNA : deoxyribose nuleic acid, which carries genetic information; it is composed of nucleotides. Isotope : a variation of an element that differs in the number of parts it possesses, more specifically the number of subatomic particles called neutrons. Radiocarbon dating : a technique that measures the age of an object containing carbon by measuring the decay of the radioactive isotope carbon

Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order. Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks.
