Question

The acid rain destroys vegetation because it contains

• A. Nitrates
• B. H${}_2$SO${}_4$
• C. O${}_3$
• D. CO

Answer 1

Answer: (B)

H${}_2$SO${}_4$

Acid rain is a formed due to the mixing of oxides of several harmful gases with the rain. Acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide and nitrogen oxides resulting from fossil fuel combustion. These gases react in the atmosphere with water, oxygen, and other chemicals to form various acidic compounds.

When this rain falls on the soil, the soil becomes acidic. Also, the leaves get destroyed and germinating seeds get corroded. Plants experience stunted growth. Thus, vegetation is destroyed.

So, the correct answer is option B.
