Solution

The correct options are
A affects pH balance of soil
B intoxicates lakes, streams and ponds
Acid rain comprises of chemicals such as sulphur dioxide and nitrogen oxide mixed with water vapour. When it rains, the water droplets containing these acidic pollutants have harmful effects on the environment. Because of their acidic nature, they affect the pH balance of the soil, thus degrading the quality of crops. Additionally, acid rain causes skin diseases, asthma and eye irritation. It also damages vehicles and buildings.

Q. Read the passage and answer the following questions:
Acid rain is formed after the burning of fossil fuels releases compounds containing nitrogen and sulfur into the atmosphere. Sunlight and rain bring about chemical reactions that convert these compounds into nitric acid and sulfur dioxide, which combine with water droplets to form acid rain. Acid rain typically has a pH of approximately 5.5. "The higher acidity of soil and water affects many living organisms adversely. As the pH of lake water falls, fish become ill and die. Table 1 shows the effects of pH on the size of adult fish.

pH of lake	Average length of fish (cm)	Average mass of fish (g)
7.5	30 cm	454 g
7.0	28 cm	450 g
6.5	29 cm	453 g
6.0	25 cm	401 g
5.5	20 cm	288 g
5.0	17 cm	127 g
4.5	All fish died	All fish died

Mycorrhizal fungi, which form a mutualistic association with many plant roots, are particularly sensitive to the effects of acid rain. These fungi facilitate the
absorption of water and nutrients by the plants; in turn, the plants provide sugars and amino acids without which the fungi could not survive.

What might be the best strategy to prevent the death of the fishes?

Q. Acidity of soil and water bodies decreases due to acid rain.

The burning of fossil fuel produces acidic oxides of Carbon, Nitrogen & Sulphur which causes acid rains which affect our water and soil resources.
