Question

YALL PLEASE HELP ME OUT!!!!Carbon dating is not used for samples that are older than 50,000 years . Why do you think that is? (Hint : Look much carbon -14 is left by the 10 ^ h half -life ). (Question is the last one on paper

Answer 1

Because of the short length of the carbon-14 half-life, carbon dating is only accurate for items that are thousands to tens of thousands of years old. Most rocks of interest are much older than this. Geologists must therefore use elements with longer half-lives.
