extinction

D.
geologic time scale

Radiometric dating is an aging process which is used to age rocks and other objects associated with them. This is based upon the decay process of radioactive isotopes present in the rocks. The radioactive decay is the process in which an unstable nucleus loses it's energy in the form of emerging radiation. The age of the typical rock is determined by the half life of the decayed products.
