Radiometric dating method definition
However, some elements are not completely stable in their natural state.
Some of the atoms eventually change from one element to another by a process called radioactive decay.
He is presently employed in the Space & Atmospheric Sciences Group at the Los Alamos National Laboratory.
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.
Most of the elements in nature are stable and do not change.There are over forty such techniques, each using a different radioactive element or a different way of measuring them.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.Radiometric dating can be compared to an hourglass.When the glass is turned over, sand runs from the top to the bottom.
