How can radiometric dating of meteorites determine the age of the earth? Wouldn’t this only determine the age of the decaying nuclide in each rock?
Planetary FormationThe Principles of Radiometric Dating Radiometric dating is a powerful technique used in geochronology to determine the age of rocks and minerals. It is based on the principles of radioactive decay, the spontaneous disintegration of unstable atomic nuclei, and the concept of half-life, the time it takes for half of a radioactive substance to decay.
