Question

Acid rain is caused due to increase in the concentration of ______ and ______.

Answer 1

Acid rain is caused due to increase in the concentration of SO₂ and NO₂.

Explanation:

The burning of coal and emissions from motor vehicles and industries release sulphur dioxide and nitrogen oxides into the atmosphere. These gases react with water vapor in the air to form sulphuric and nitric acids, which then fall to the ground as acid rain. Acid rain increases soil acidity, harms aquatic life by acidifying lakes and streams, and damages crops, human health, and structures like buildings and monuments.
