Radiometric dating is also used to date archaeological materials, including ancient artifacts.

Radiometric dating methods are used to establish the geological time scale.

It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.

Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.

He was employed at Caltech's Division of Geological & Planetary Sciences at the time of writing the first edition.

He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.

Geologists overcome this problem by ‘interpreting’ the result.

It is important to realize that the laboratories do not measure the ‘age’ of the rocks but the isotopes in them at the present time.

Geologists calculate an ‘age’ using the measured amount of a ‘daughter’ isotope (e.g.

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.

Elements exist in different isotopes, with each isotope of an element differing in the number of neutrons in the nucleus.
