Question

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

GPT-5 mini · Answer

Amount of carbon-14 and nitrogen-14 in the remains.

Explanation: Radiocarbon dating measures how much radioactive carbon-14 has decayed (into nitrogen-14) compared with remaining carbon to calculate the absolute age of once‑living material (effective to ~50,000 years). The other choices describe methods or clues used for dating rocks or are not applicable to organic remains.
