← GeographyWhich consequence results when increased bioturbation rates occur?
A)Enhanced soil horizon structural homogeneity✓
B)Reduced nutrient availability near surface
C)Decreased weathering of parent bedrock
D)Weaker aggregate stability in topsoil
💡 Explanation
Bioturbation mixes soil layers, leading to homogenization because the disturbance decreases differentiation; therefore, uniform layering replaces sharp horizon distinctions, rather than reduced nutrients or inhibited weathering.
