When Rutherford announced his findings it soon became clear that Earth is millions of years old.
These scientists and many more after them discovered that atoms of uranium, radium and several other radioactive materials are unstable and disintegrate spontaneously and consistently forming atoms of different elements and emitting radiation, a form of energy in the process.
The original atom is referred to as the parent and the following decay products are referred to as the daughter.
For example: after the it forms a component of all organic compounds and is therefore fundamental to life. Libby of the University of Chicago predicted the existence of carbon-14 before it was actually detected and formulated a hypothesis that radiocarbon might exist in living matter.
Potassium is a component in many common minerals and can be used to determine the ages of igneous and metamorphic rocks.Zircons will loose their tracks at higher temperatures of 200.The tracks will then begin to accumulate when the rock begins to cool.If the rock containing these minerals is heated, the tracks will begin to disappear.
