Brief Facts about Ozone Layer:
The stratospheric ozone layer is composed of naturally through the interaction of solar ultraviolet radiation with molecular oxygen (O2). The ozone layer is the protection layer around the sun that is made of O3. This layer is a protective wall that filters the harmful rays that come from the sun’s side. Whereas, this layer cannot bear the dangerous effects of carbon dioxide and other harmful gases that go up from various activities on Earth. This results in a hole in the ozone layer. It further results in the coming of harmful rays from the sun and causes various diseases among human beings.
