Which statement accurately describes radioactive dating?
vitfil [10]

Answer:

D. Geologist compare the observed abundance of naturally occurring radioactive isotopes and their decay products using decay rates.

Explanation:

Radioactive dating is the method in which radioactive isotopes are employed to evaluate the age of rocks and ores. There are many complex radioisotopes utilized for radioactive dating is like Potassium, Uranium, and Carbon. Radioactive dating operates on the system that a radioactive isotope can fade into the constant daughter nuclei at a steady rate. Geologist commonly uses the system for half life. Half-life is the time needed for half of the radioactive element to decline. This is fixed for a selective element.
