Final answer:

Radioactive dating involves determining the age of rocks and fossils by measuring the decay of radioactive materials within them. It can provide accurate estimates of the age of geological materials by analyzing the ratio between parent and daughter isotopes and calculating how many half-lives have passed. This process is used to determine geologic time and the estimated age of objects such as rocks, minerals, and fossils.
