(ii) Sulfur trioxide forms a mixture of fog known as smog that affects the eyes also.
(iii) Acid rain damages the wildlife in the ecosystem where it falls.

(i) The greenhouse effect is the process of trapping the Sun’s heat by some atmospheric gases. - False
(ii) Sulfur trioxide forms a mixture of fog known as smog that affects the eyes also.- True
(iii) Acid rain damages the wildlife in the ecosystem where it falls.- True
