Ozone life cycle

16 Sep 2015

The ozone (O3) is the combination of an oxygen molecule (O2) and an oxygen atom (O). The life cycle of ozone starts from breaking apart of the oxygen molecule (O2) by UVC radiation into two oxygen atoms (O +O), and the oxygen atom (O) reacts with other oxygen molecules (O2) to reform ozone. The UVB radiation, then, breaks the ozone molecules (O3) into the oxygen molecule (O2) and the oxygen atom (O). This life cycle plays in accordance with the balance of nature.
