September 30, by Beth Geiger. Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life. Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e. Comparisons between the observed abundance of certain naturally occurring radioactive isotopes and their decay products, using known decay rates, can be used to measure timescales ranging from before the birth of the Earth to the present.

Most absolute age determinations in geology rely on radiometric methods.
Geologists often need to know the age of material that they find. As a member, you'll also get unlimited access to over 79, lessons in math, English, science, history, and more. Cart 0.
