Isotopic age dating dating el

Based on our study of meteorites and rocks from the Moon, as well as modeling the formation of planets, it is believed (pretty much well-established) that all of the objects in the Solar System formed very quickly about 4.56 billion years ago.When we age date a planet, we are actually just dating the age of the surface, not the whole planet.those that form during chemical reactions without breaking down).

For geological purposes, this is taken as one year.

This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.

This radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate.

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.

This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Some do not change with time and form stable isotopes (i.e.
