Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.
Statement I:Acid rain occurs within, and downwind of, areas of major industrial emissions of sulphur dioxide and oxides of nitrogen.
Statement II:Long range transport of airborne pollutants can be responsible for acid rain in areas far off from industrial emissions.
ABoth Statement I and Statement II are correct ✓ Correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect
DStatement I is incorrect but Statement II is correct
Correct answer: (A) Both Statement I and Statement II are correct
Explanation
Acid rain forms where sulphur dioxide and nitrogen oxides are emitted, and also far downwind of them.
Statement 1 is correct because these gases turn to acids near and downwind of industrial sources.
Tall chimneys push the pollutants high, letting winds carry them well beyond the source area.
Statement 2 is correct because long-range transport can drop acid rain in distant, cleaner regions.
This is why forests and lakes far from any factory can still suffer acidification.
Scandinavian lakes were acidified by emissions carried from industrial Britain and Europe.
