Question

Which of the following is a method used to obtain the absolute age of a rock or fossil?

Answer 1

carbon reading maybe?

Answer 2

^ Carbon dating is the best method because it uses concrete chemical 'evidence'.

Answer 3

actually it is radioactive carbon dating or you can say c14* dating.any organic compound is made up of carbon,now if we measure the rate of disintegration of c14* to normal c12 carbon,by acquring the half life or % of c14*/c12 ratio.we can easily obtain the age of that fossil.
