Detailed explanation-1: -Radiometric dating is referred to as absolute dating because it gives scientists a precise age of a rock sample based on known, measurable factors and the exact half-life of radioactive isotopes in the rock.
Detailed explanation-2: -Absolute dating methods measure the physical properties of an object itself and use these measurements to calculate its age. One of the most useful absolute dating methods for archaeologists is called radiocarbon dating.
Detailed explanation-3: -The unstable radioisotope is sometimes referred to as the parent isotope and the decay product is referred to as the daughter isotope. Radiometric dating is also called radioisotope dating or radioactive dating because it measures the radioactive isotopes left in the object.
Detailed explanation-4: -Radiometric dating is a method of establishing how old something is – perhaps a wooden artefact, a rock, or a fossil – based on the presence of a radioactive isotope within it.
