How do scientist use radioactive isotopes for radioactive dating?

Scientists use radioactive isotopes in minerals to determine the age of rocks and fossils through a process called radiometric dating. By measuring the ratio of the parent isotope to the daughter isotope, scientists can calculate the age of a sample based on the known decay rate of the radioactive isotope. This method is commonly used in geology, Archaeology, and Paleontology to determine the age of Earth materials.
