← GeographyWhich environmental change occurs when intense bioturbation inhibits pedogenesis?
A)Horizon differentiation decreases significantly✓
B)Cation exchange capacity increases rapidly
C)Organic matter decomposition accelerates
D)Silicate clay mineral formation increases
💡 Explanation
Intense bioturbation disrupts soil structure, reducing horizon differentiation because it homogenizes soil layers, impeding the formation of distinct soil horizons. Therefore, horizon definition decreases, rather than increased organic matter or silicate formation, which need stable layers.
