Essa si basa sul raffronto tra le abbondanze osservate di un opportuno isotopo radioattivo e dei suoi prodotti di decadimento (noto il tempo di dimezzamento, ed è la principale fonte di informazioni sull'età della Terra e sulla velocità dell'evoluzione delle specie viventi).Esistono vari metodi di datazione radiometrica, differenti nella precisione della misura, nei costi e nelle scale temporali per le quali possono essere utilizzati.Slowly and painstakingly, geologists have assembled this record into the generalized geologic time scale shown in Figure 1.This was done by observing the relative age sequence of rock units in a given area and determining, from stratigraphic relations, which rock units are younger, which are older, and what assemblages of fossils are contained in each unit.

Rb)—are not being formed on earth, as far as we know.Dopo un tempo pari al tempo di dimezzamento, metà degli isotopi radioattivi sono decaduti.efore analyzing the arguments advanced by creation “scientists” for a very young Earth, I here summarize briefly the evidence that has convinced scientists that the Earth is 4.5 to 4.6 billion years old.Using fossils to correlate from area to area, geologists have been able to work out a relative worldwide order of rock formations and to divide the rock record and geologic time into the eras, periods, and epochs shown in Figure 1.The last modification to the geologic time scale of Figure 1 was in the 1930s, before radiometric dating was fully developed, when the Oligocene Epoch was inserted between the Eocene and the Miocene.
