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. magnetic
B. relative
C. Precambrian
D. absolute

Answer 1

Answer: D. absolute

Step-by-step explanation:

Absolute dating can be define as the method of dating in which the chronological age of the fossil or rock can be determined on the basis of radioactive carbon dating. The radioactive carbon is the element which decays after the death of the organism. The half life can be determined on the basis of the decay process which can be linked with the age of evidence.

Answer 2

The answer would be known as absolute dating
