Question

Radioactive isotopes in fossils decay at a constant rate. The ratio of radioactive isotope to stable isotope can be examined to estimate the age of the fossil or the rock it was found in. This is an example of _______ dating.

A. relative
B. Precambrian
C. absolute
D. magnetic

Answer 1

Radioactive isotopes in fossils decay at a constant rate. The ratio of radioactive isotope to stable isotope can be examined to estimate the age of the fossil or the rock it was found in. This is an example of C. Absolute dating.

Answer 2

The correct answer is option C, that is, absolute.

Step-by-step explanation:

A method of dating in which the chronological age of the rock or the fossil can be predicted based upon the radioactive carbon dating is known as absolute dating. The radioactive carbon refers to the element that dissociates or degrades after the organism's death. The determination of the half-life can be done on the basis of the process of decay that can be associated with the age of proof.
