Radiometric dating is a widely used method for age dating in geology because it relies on the principles of radioactive decay. This technique allows geologists to determine the age of rocks and organic materials by measuring the abundance of specific isotopes and their decay products. For instance, by analyzing isotopes like carbon-14, uranium-238, or potassium-40, geologists can establish a timeline for geological events, effectively dating the formations and fossils found within the Earth.

Radiometric dating is particularly valuable because it can provide absolute ages in years, as opposed to relative dating methods that only indicate whether one rock layer is older or younger than another. This precision is crucial for understanding the geological history of the Earth, including the timing of events like volcanic eruptions, the formation of sedimentary layers, or the age of fossils.

The other methods listed, while potentially useful in different contexts, do not serve as primary techniques for age dating in the same way radiometric dating does.
