← GeographyWhich outcome results from slow rates of oxidation during pedogenesis?
A)Accumulation of ferrous iron✓
B)Intense clay mineral weathering
C)Rapid humus decomposition rate
D)Increased rate of soil erosion
💡 Explanation
The accumulation of ferrous iron occurs because redox reactions slow during pedogenesis due to limited free oxygen during weathering; this causes a reducing rather than oxidizing environment therefore increased ferrous iron levels, rather than iron oxidation reactions.
