Note that, contrary to a popular misconception, carbon dating is not used to date rocks at millions of years old.Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.­The carbon-14 atoms that cosmic rays create combine with oxygen to form carbon dioxide, which plants absorb naturally and incorporate into plant fibers by photosynthesis.

­ ­You probably have seen or read news stories about fascinating ancient artifacts.

At an ar­chaeological dig, a piece of wooden tool is unearthed and the archaeologist finds it to be 5,000 years old.

Carbon-14 is radioactive, with a half-life of about 5,700 years.

For more information on cosmic rays and half-life, as well as the process of radioactive decay, see How Nuclear Radiation Works.

Co­smic rays enter the earth's atmosphere in large numbers every day.

For example, every person is hit by about half a million cosmic rays every hour.Protons and neutrons make up the center (nucleus) of the atom, and electrons form shells around the nucleus.The number of protons in the nucleus of an atom determines the element.It is not uncommon for a cosmic ray to collide with an atom in the atmosphere, creating a secondary cosmic ray in the form of an energetic neutron, and for these energetic neutrons to collide with nitrogen atoms.When the neutron collides, a nitrogen-14 (seven protons, seven neutrons) atom turns into a carbon-14 atom (six protons, eight neutrons) and a hydrogen atom (one proton, zero neutrons).This assumption is backed by numerous scientific studies and is relatively sound.

  1. All models that appear in any visual portrayal appearing on, or otherwise contained in, this Website were over the age of eighteen (18) years at the time the visual portrayal was produced. 2257 records are available from the sponsors these galleries were provided by, links to records are located on the bottom of galleries.

  2. There are more side effects that may threaten student health when they take excessive amounts of alcohol, energy drinks, oxycontin, cold medicine and marijuana.

  3. Colloquially, one inch under this is considered short.

  4. Free IPA consists of many integrated technologies and components.

  5. I enjoy romantic walks along the beach, candle light dinners.

  6. This site looks best with a screen resolution (the size of what is shown) of 1600 x 900 HDMI.
