Radiometric dating uses ratios of isotopes in rocks to infer the age of the rock scientists use a mix of observational data and assumptions about the past to determine the radiometric age of a rock comparing the amount of a parent isotope to the amount of its daughter isotope and knowing the rate of change from parent into daughter (known as.
