← GeographyWhich soil property results when continuous water saturation arrests pedogenesis?
A)Gleying and increased iron concentrations✓
B)Calcification reduces subsurface water permeability
C)Salinization drives clay aggregate formation
D)Podzolization decreases upper horizon pH
💡 Explanation
Gleying occurs because anaerobic conditions due to permanent saturation inhibit typical redox reactions during pedogenesis. Therefore, iron remains in a reduced state causing a grey/green color, rather than other processes facilitated by oxidation.
