In historical geology, the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young (radiocarbon dating with Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes.Particular isotopes are suitable for different applications due to the type of atoms present in the mineral or other material and its approximate age.The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century.No other scientific method has managed to revolutionize man’s understanding not only of his present but also of events that already happened thousands of years ago.Age dating the Earth (Geochronology) is the scientific study of the age of the Earth and the temporal sequence of events related to the formation of the planet and the history of life on Earth.

The word is derived from Geo meaning Earth, and chronology, which is the study of time, or a record of events in the order of their occurrence (timeline).
