When ‘parent’ uranium-238 decays, for example, it produces subatomic particles, energy and ‘daughter’ lead-206.

Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.

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.

There are two main methods determining a fossils age, relative dating and absolute dating.

These were then eroded and Sedimentary Rocks B were deposited.Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.The atoms of some chemical elements have different forms, called isotopes.These break down over time in a process scientists call radioactive decay.

Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
