What environmental issue can result from acid precipitation?

Acid precipitation, commonly referred to as acid rain, primarily results from the emission of sulfur dioxide and nitrogen oxides into the atmosphere, which then combine with water molecules to create acidic compounds. This environmental issue has several significant impacts, one of which is the corrosion of buildings and infrastructure.

Many buildings, especially those made from limestone, marble, and other calcareous stones, are particularly vulnerable to the harmful effects of acid rain. The acid reacts chemically with the minerals in the stone, leading to deterioration, structural damage, and aesthetic degradation. Over time, this corrosion not only compromises the integrity of the buildings but also requires costly repairs and maintenance.

In contrast, increased soil fertility and enhanced plant growth are generally not accurate outcomes of acid precipitation. Acid rain tends to leach essential nutrients from the soil, such as calcium and potassium, which can harm plant life rather than promote growth. Flooding of urban areas is also unrelated, as while acid rain can contribute to pollution, it does not directly cause flooding. Hence, corrosion of buildings reflects one of the critical and direct consequences of acid precipitation on our environment.
