Question

_________________occurs when acid rain adds hydrogen ions to the soil which interact chemically with existing minerals.

Answer 1

Nutrient leaching:

• Acid rain affects soil chemistry and water bodies.
• The most important effects of acid rain on forests are due to nutrient leaching, accumulation of toxic metals, and the release of toxic aluminium.
• Nutrient leaching occurs when acid rain adds hydrogen ions to the soil which interact chemically with existing minerals.
• This displaces Ca, Mg and K from soil particles and deprives trees of nutrition.

Hence, nutrient leaching occurs when acid rain adds hydrogen ions to the soil which interact chemically with existing minerals.
