Dating an object using radioactive isotopes
WebJun 4, 2024 · Radiometric dating is a means of determining the age of very old objects, including the Earth itself. Radiometric dating depends on the decay of isotopes, which … WebOct 1, 2009 · Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate. To date a radioactive rock, geologists first measure the “sand grains” in the top glass bowl (the parent radioisotope, such as uranium-238 or potassium-40).

WebApr 16, 2024 · Absolute dating or radiometric dating is a method used to determine the age of rocks by measuring its radioactive decay. A radioactive isotope in the rock decays into a stable daughter isotope. The decay occurs at a predictable rate, so the age of the sample could be determined. Webabsolute-age dating enables scientists to determine the numerical age of rocks and other objects radioactive decay The emission of radioactive particles and the resulting change into other isotopes over time radiometric dating When scientists date an object using radioactive isotopes. half-life
