उत्तर
Stratospheric ozone or good ozone is a layer surrounding the earth’s atmosphere. It protects all life on earth from the damaging effects of the sun’s rays. Ground level ozone is formed by a photochemical reaction between atmospheric oxygen (O2) and smog forming chemicals at the earth’s surface, it is odourless and colourless, but can have profound effects on the human respiratory system.
