BIO112 Spring 2024 Exam 1 Terms radiometric dating general approach used to determine the age of specimens using the rate of decay of radioactive isotopes radiocarbon dating a chemical analysis used to determine the age of organic materials based on their content of the radioisotope carbon-14 potassium-40 dating radiometric dating method often used in the assessment of volcanic intrusions in sedimentary layers. It is based on measurement of the product of the radioactive decay of an isot...
