NettetThe ozone layer is mainly found in the lower portion of the earth’s atmosphere. It has the potential to absorb around 97-99% of the harmful ultraviolet radiations coming from the sun that can damage life on earth. If the ozone layer was absent, millions of people would develop skin diseases and may have weakened immune systems. Nettet(a) Ozone is made up of three atoms of oxygen combined together. It is formed high up in the atmosphere by the action of ultraviolet (UV) radiation on oxygen gas. The UV radiation from the sun splits the oxygen gas into free oxygen atoms.
