How does radioactive decay related to radiometric dating

radioactive decay related to radiometric dating - Addition to the ages of earth, moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of earth's magnetic field, and the age and duration of a wide variety of other geological events and processes. Sun alters radioactive decay rates many scientists rely on the assumption that radioactive elements decay at constant, undisturbed rates and therefore can be used as reliable clocks to measure the ages of rocks and artifacts. Radioactive parent atoms decay to stable daughter atoms (as uranium decays to lead) each disintegration results in one more atom of the daughter than was initially present and one less atom of the parent. The number of parent atoms originally present is simply the number present now plus the number of daughter atoms formed by the decay, both of which are quantities that can be measured.
