← GeographyWhich soil profile change occurs when excessive rainfall affects recently deposited volcanic ash?
A)Increased horizon differentiation
B)Reduced mineral weathering
C)Limited clay mineral formation✓
D)Accelerated organic matter accumulation
💡 Explanation
Limited clay mineral formation occurs due to rapid leaching by rainfall, primarily removing silicon and aluminum during Intense desilication rather than synthesizing secondary minerals because high moisture levels prevent optimal pedogenesis; therefore, this inhibits forming structured clay layers rather than promoting differentiation.
