← GeographyWhich outcome occurs when acidic rainfall accelerates pedogenesis in basaltic rock?
A)Mobilization of iron and aluminum✓
B)Formation of silcrete layers
C)Accumulation of gypsum deposits
D)Deposition of thick peat layers
💡 Explanation
Acidic rainfall drives chemical weathering, which releases ions more readily. Eluviation, a key part of pedogenesis, mobilizes iron and aluminum because acidic solutions dissolve these minerals readily; therefore, iron and aluminum oxides accumulate,rather than silcrete, gypsum, or peat forming which require different geochemical conditions.
