Explain how radiometric dating is used to estimate absolute age?
Radiometric dating is based on the principle that certain isotopes decay at a constant rate over time. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can calculate how much time has passed since the rock formed. This method provides an accurate estimate of the absolute age of the rock or fossil.
