← GeographyWhich process is accelerated as a consequence of increased bioturbation?
A)Humus layer nutrient mobilisation✓
B)Caliche layer accelerated precipitation
C)Glacial till sediment compaction
D)Alluvial fan deposition rates
💡 Explanation
Increased bioturbation mixes the soil and enhances aeration; this accelerates humus breakdown via oxidation because microorganisms obtain easier access to organic matter, therefore leading to faster nutrient mobilisation rather than compaction or deposition which are differently influenced.
