Answer: The ozone layer is a thin blanket surrounding the atmosphere, comprised of three atoms of oxygen and is denoted by O₃. It is found in the layer of stratosphere, that helps us in protecting from the harmful UV radiations released from the sun.
Ozone layer has been depleted over the last few years, and this is due to the increasing amount of green house gases in the atmosphere. Due to this thinning of the ozone layer, the incoming solar radiation affects the human skin thereby causing severe problems.
Over the last few years, these green house gases has been increasing at a considerable rate, such as the emissions from the vehicles, from the industries and factories as well as burning up of fossils at a higher rate.
Thus, the ozone layer is becoming thin at the upper atmosphere.
