← GeographyWhich consequence results when acidic rainfall accelerates podzolisation?
A)Increased aluminum ion soil concentration✓
B)Accelerated organic matter decomposition rate
C)Enhanced soil aggregate formation stability
D)Decreased base cation nutrient availability
💡 Explanation
Increased acidity triggers leaching, enhancing podzolisation, because the increased hydrogen ions displace aluminum ions in clay minerals via cation exchange. Therefore aluminum solubility increases, rather than being retained in the soil matrix in stable forms.
