The isotopes in Table below are used to date igneous rocks.

The first weird requires understanding the paramount order of the field layers.

These remains are subjected to dating techniques in order to predict their ages and trace their history.

Absolute dating provides a numerical age or range in contrast with relative.

Absolute ages are much different from relative ages. Absolute ages are determined by radiometric methods, such as carbon-14 dating. Radioactive decay is the breakdown of unstable elements into stable elements. But carbon-12 has 6 neutrons and carbon-14 has 8 neutrons. Neutrons in cosmic rays strike nitrogen atoms in the atmosphere. Carbon in the atmosphere combines with oxygen to form carbon dioxide.

To understand this process, recall that the atoms of all elements contain the particles protons, neutrons, and electrons. Plants take in carbon dioxide during photosynthesis. Like other unstable isotopes, carbon-14 breaks down, or decays.
