Web29 jun. 2024 · Earth Science Evidence about Earth's Past Absolute Ages of Rocks 1 Answer David Drayer Jun 29, 2024 Radioactive decay can be used to date igneous rocks by assuming making some assumptions, finding the percentages of parent to daughter products and using experimentally determined half-lives. Explanation: WebThe activity of a radioactive sample can be regarded as a probability as much as it is a rate. It is measured in Ci (curies), Bq (becquerels) or other units. The half-life of a radioactive nucleus is the time it takes to halve the number of decaying nuclei in a sample of any size. fitness for ladies gordon
