High School Biology: Help and Review. College Biology: Help and Review. Lesson Transcript.
Discover how scientists determine the age of fossils, rocks, and other geologic phenomena by using the known half-lives of isotopes within each specimen, a technique known as radioactive dating.
Radioactive Dating Ever wonder how scientists concluded the age of the earth to be about 4. Radioactivity Defined Elements occur naturally in the earth, and they can tell us a lot about its past. The Half-Life Isotopes decay at a constant rate known as the half-life. Try it risk-free No obligation, cancel anytime.
Want to learn more? Radiocarbon Dating Since all living things contain carbon, carbon is a common radioisotope used primarily to date items that were once living. Lesson Summary So, to sum this all up, radioactive dating is the process scientists use to conclude the ages of substances dating back several to many years ago by using the isotopes of elements and their half-lives.
