Using the known rates of radioactive decay to date the crystallization of certain minerals is known as dating. a. Conventional
b. Radiometric
c. Relative
d. Fossil assemblage

The correct answer is: b. Radiometric.

Explanation:

Radiometric dating, or radioactive dating, is a method that is utilized to learn the age of materials such as rocks by comparing the known affluence of a naturally occurring radioactive isotope with its decay products, which are formed at known constant rates. This means that they understand how old a material is by looking at how fast its radioactive components decay.

Radiometric dating is used by setting geological timescales and thus, it supplies with a great amount of information about the date of fossils, among other things.
