Creation v. Evolution: How Carbon Dating Works As the rock starts to age, rubidium gets converted to strontium. Some Naturally Occurring Radioactive Isotopes and their half-lives. Radiometric dating is based on index fossils whose dates were assigned long before radioactivity was discovered. The only two quantities in the exponent of a radiometric dating dinosaurs rate equation are the half-life and the time. Onlyheisgood The point is not that the method is wrong. This is the same as the initial amount it would not change if there were no parent isotope to decay.
Interactions between plates cause the formation of. After two half-lives one-fourth remains, after three half-lives, one-eighth, etc.
