A. Measuring radioactive decay of element isotopes

B. Comparing the rock to other geologic features

C. Measuring the dimensions of the rock

D. Comparing the rock to similar rocks and noting the differences

Respuesta :

A) Scientists measure the radioactive decay of the elment isotpes.

Answer;

Measuring the radioactive decay of element isotopes.

The primary technique for determining the absolute age of a rock is the measuring the radioactive decay of element isotopes.

Explanation;

The measuring of the radioactive decay of element isotopes to determine the age of rocks is called Radiometric Dating.

Radiometric dating is a method of determining the absolute age of an object such as rocks by comparing the relative percentages of a radioactive (parent) isotope and a stable (daughter) isotope.
