When the radioactive date contradicts the relative age as determined by the fossils the fossil date is always considered to be the better value. No geologist uses radioactive dating to do more than confirm dates established by the fossils using Darwins theory of descent with modification.

What is the difference between radioisotope radioactive dating and relative dating?

The difference between relative dating and radioactive dating is that the relative dating cannot provide actual numerical dates whereas the radioactive dating can provide actual numerical dates.

What is the difference between radiometric and radioactive?

Radiometric dating, often called radioactive dating, is a technique used to determine the age of materials such as rocks. It is based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
