← GeographyWhich process accelerates surface pedogenesis during glacial retreat?
A)Enhanced physical weathering processes✓
B)Reduced biogeochemical cycling speeds
C)Suppressed fluvial terrace formation
D)Decreased aeolian sediment deposition
💡 Explanation
Glacial retreat exposes fresh rock surfaces causing accelerated weathering of underlying bedrock; fracturing from ice expansion enhances physical weathering processes. Therefore, pedogenesis quickens, rather than slower biogeochemical cycling because more fragmented material leads to faster breakdown.
