The technique called radiometric dating is based on
A) the steady, clocklike decay of certain radioactive isotopes over time.
B) the assumption that radioactive isotopes accumulate in fossils at a constant rate.
C) the formation of radioactive molecules in rocks after they are deposited.
D) the use of fossils of known age to determine how fast carbon-14 decays.

Question

Quizplus · Accepted Answer

Radiometric dating is based on the steady, clocklike decay of certain radioactive isotopes over time. By measuring the amount of parent and daughter atoms in a sample, scientists can determine how long it has been since the rock or mineral was formed. This technique is widely used to date rocks, fossils, and other geological materials.
