How do geologists use carbon dating to find the age of rocks?
These radioactive isotopes are unstable, decaying over time at a predictable rate. As the isotopes decay, they give off particles from their nucleus and become a different isotope. The parent isotope is the original unstable isotope, and daughter isotopes are the stable product of the decay.
determining the age of a fossil by radioactive elementsHeather Scoville is a high school science teacher and writes science curriculum for online science courses. Updated January 27, 2019 Perhaps the most widely used evidence for the theory of evolution through natural selection is the fossil record. The fossil record may be incomplete and may never fully completed, but there are still many clues to evolution and how it happens within the fossil record. One way that helps scientists place fossils into the correct era on the geologic time scale is by using radiometric dating. Also called absolute dating, scientists use the decay of radioactive elements within the fossils or the rocks around the fossils to determine the age of the organism that was preserved.

Dinosaurs disappeared about 65 million years ago. That corn cob found in an ancient Native American fire pit is 1,000 years old. How do scientists actually know these ages?
