Question

Quizplus · Accepted Answer

Radiometric dating is based on the steady and clocklike decay of certain radioactive isotopes over time. By measuring the amount of remaining radioactive isotopes and knowing their half-life, scientists can determine the age of rocks and fossils. Option A is incorrect because radiometric dating doesn't use fossils of known age. Option B is incorrect because the rate of accumulation of radioactive isotopes can be affected by various factors, such as changes in environment and geological processes. Option D is incorrect because radioactive molecules are already present in rocks when they are formed, not after they are laid down.
