← GeographyWhich outcome occurs when acidic rainwater saturates basalt?
A)Accelerated mobilization of clay minerals✓
B)Increased rate of carbon sequestration
C)Decreased levels of evaporite formation
D)Slower rates of mechanical weathering
💡 Explanation
The leaching process mobilizes ions; basalt weathering frees hydroxyls neutralizing local soil, therefore increasing clay dispersion, because acidic water dissolves minerals that then migrate downward due to the altered ionic potential, rather than the other listed outcomes.
