Explain the process of Ozone formation in atmosphere.

Explanation

Ozone is found in the layer of the atmosphere called the Stratosphere. It acts as a protective covering that absorbs ultraviolet (UV) radiation from the Sun. The ozone molecule `(O_(3))` consists of three oxygen atoms. It is formed when atmospheric oxygen `(O_(2))` on exposure to solar radiation breaks into two oxygen atoms, each atom then joins up with a single oxygen atom. The ozone molecule is unstable. It soon decays again to form molecular oxygen. This cycle is a continuous process in the upper reaches of the stratosphere.
