- DDue to ozone depletion less amount of UV radiations reaches to earth surface.
Correct answer
D. Due to ozone depletion less amount of UV radiations reaches to earth surface.
Step-by-step solution
The 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. Due to ozone depletion high amount of UV radiations reaches to earth surface
