A. seafloor spreading at mid-ocean ridges
Geologists can determine the actual age of features on a planet by the radiometric dating method in which the age of the rocks is calculated by the natural decay of the radioactive isotopes of elements such as carbon.
In the radiometric dating method, the radioactive minerals in rocks are used. The radioactive isotopes, which are the chemical elements, naturally break down and decay to form a new isotope.
Each radioactive element has a unique decay rate which is known. Hence, the radioactive isotopes are crucial for the geologist to compare and identify the age of the rocks and furthermore, the planet.
