Radiometric dating is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes. Layers that cut across other layers are younger than the layers they cut through principle of cross-cutting relationships. Each isotope is identified by its atomic mass , which is the number of protons plus neutrons. Absolute radiometric dating requires a measurable fraction of parent nucleus to remain in the sample rock. During magnetic reversals, there are probably changes in convection in the Earth's core leading to changes in the magnetic field.

This field is known as thermochronology or thermochronometry.
