Which measurement do geologists use to find the absolute age of once-living things? amount of decayed daughter elements total number of half-lives for the element potassium age of ancient rocks located near the remains amount of carbon-14 and nitrogen-14 in the remains

Amount of carbon and nitrogen in the remains, this is called carbon dating.

Answer;

amount of decayed daughter elements

Explanation;Absolute age is the age of a rock in years. Absolute age is found by measuring the amount of certain radioactive elements in the rock.During the formation of rock, small amounts of radioactive elements is normally included. As the time passes, the parent radioactive elements undergo decay at a regular rate into non-radioactive daughter elements. By measuring the rate at which a parent element decays and then the ratio of parent element to daughter element in the rock the age of rock in years can be found.
