The Depletion of Ozone Layer Ozone is a natural trace component of the atmosphere. It is created continuously through the action of sunlight and oxygen in the upper atmosphere. At the same time this destroyed by various reactions with other components in the air. The next result of these natural processes is the so-called ozone layer in the stratosphere at altitudes between 15 and 50 kilometers in which the concentration of the ozone is raised. Ozone is a colorless gas, a form of oxygen. However, an ordinary molecule of oxygen contains two atoms. Because of ozone’s composition, it is reactive. It readily combines with whatever materials it comes in contact with, including
