Ozone (O3) in the air is a molecule made up of three oxygen atoms. It is a form of oxygen that occurs naturally in the Earth's atmosphere. Ozone plays a crucial role in the stratosphere, where it absorbs most of the sun's harmful ultraviolet (UV) radiation, protecting life on Earth from its damaging effects. However, ground-level ozone, formed as a result of chemical reactions between pollutants emitted by vehicles, industrial processes, and other sources, can be harmful to human health and the environment.
