← GeographyWhich weathering outcome significantly slows blanket bog pedogenesis?
A)Iron pan formation retarding drainage✓
B)Extreme insolation intensifying surface erosion
C)Cryoturbation enhancing mineral breakdown rate
D)Calcareous material accelerating decomposition
💡 Explanation
Iron pan formation impedes water percolation needed for decomposition, leading to slower pedogenesis, because the iron pan acts as an impermeable layer that restricts drainage. Therefore, blanket bog development is retarded, rather than accelerated by other weathering processes.
