The igneous activity that produced such intrusions......calculation was based on the assumption that the substance of the Earth is inert and thus incapable of producing new heat.Additionally, elements may exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.

Radiometric dating is a process of identifying the age of a material based on known half-lives of decaying radioactive materials found in both organic and inorganic objects.

Radiometric dating is often used to determine the age of rocks, bones, and ancient artifacts.

Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.

All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.

In fact, radiometric dating can be used to determine the age of the Earth, (5.54 billion years old) other planets, and celestial objects.
