Which of the following statements accurately describes the process of dating Earth history?
A. Scientists use index fossils to determine the specific years of age of a new fossil.
B. Scientists use relative dating to determine the absolute age of a new fossil.
C. Scientists use radioactive isotopes to determine the absolute age of a new fossil.
D. Scientists use radiometric dating to determine the relative age of a new fossil
Answer: C.
Using radioactive isotopes, which decay at a steady rate,
scientists can find the age in years of a sample. This technique takes advantage of the
fact that different radioactive isotopes have diffe
