OZONE LAYER


Ozone is a gas naturally present in Earth’s atmosphere. Unlike regular oxygen, which contains two oxygen atoms (O2), ozone contains three oxygen atoms (O3). A molecule of regular oxygen can be converted to O3 by UV radiation, electrical discharge (such as from lighting) or complex chemical reactions. These processes split apart the two oxygen atoms, which are then free to bind with other loose oxygen.
