Background - Ozone Layer
Ozone is a type of oxygen. It is an electrically charged layer of oxygen ions which have the ability to block much of the ultraviolet radiation that comes from the Sun. The Ozone Layer is an important natural component of the atmosphere. This protection has made it easier for living things to populate the land. We have evolved in a delicate range of influences and conditions. The UV radiation changes oxygen into ozone at the upper layer of the atmosphere. The Earth also replenishes the Ozone Layer with lightning storms.
