Explanation:
The stratosphere is the layer of the earth’s atmosphere which is above the troposphere and below the mesosphere.
The stratosphere contains about 90 percent of the ozone layer. The stratosphere is made up of ozone layers which helps in the absorption of about 95 percent of the ultraviolet rays from the sun and converting to heat.
This is the reason why depletion of the ozone layer found in the stratosphere gives rise to global warming.
