Answer: Radioactive decay</h2>
<u>Radioactive decay</u> is a spontaneous process in which the nucleus of an atom disintegrates, giving way to the emission of radiation and the appearance of a new nucleus, releasing energy in the process.
<u>This process is widely used in radioactive </u><u>geological dating</u> (also called <u>isotopic dating or radioisotope dating</u>) in which radioactive impurities were selectively incorporated when the fossil materials were formed.
Therefore:
Isotopic dating relies on a process called <u>radioactive decay</u>
