This is a worksheet with questions that require students to demonstrate knowledge of using radioactive dating techniques to identify the ages and/or mass remaining after a certain number of half-lives have occurred. There is a student answer sheet and teacher answer key included. Radioactive isotopes (U, 14C) can spontaneously change or decay. 4. Radiometric dating. Radiometric dating is a technique used to date materials, based on a comparison between the observed abundance of particular naturally occurring radioactive isotopes and their known decay rates. Initial radioactive isotope is called a parent. Radioactive Dating - The Bottom Line. The Solar System, Earth included, formed billion years ago as revealed by the uniform radioactive dating ages of meteorites. The oldest rocks ever found on the Earth itself are closer to billion years old, and most rocks on Earth are less than 1 billion years old.
