Answer:
O. Geologists and archaeologists use different dating processes to determine the age of rocks, fossils, and ancient artifacts.
Explanation:
Redioactive decay is the process whereby the radioactive materials reduces in quantity through the decay of its materials.
For example, if there where 100g of polonium today, and 5 years later, it has reduced to 30g, then, radioactive decay has taken place over the long period of time.
<em>One of its major use is in the determination of the ages of rocks, fossils, and ancient artifiacts through its cabon dating inorder to determining the radioactive decay of those materials over the past few decades.</em>
