← GeographyWhich consequence results when groundwater calcium carbonate saturation increases during seasonal pedogenesis?
A)Caliche layer formation accelerates upwards✓
B)Organic matter decomposition slows down
C)Capillary action within soil decreases
D)Soil aggregate stability temporarily increases
💡 Explanation
Increased calcium carbonate saturation promotes precipitation and cementation during pedogenesis, thus caliche accelerates upwards. This is driven by carbonate precipitation, rather than increased aggregation, bioturbation, or organic matter breakdown, because it is directly tied to CaCO3 solubility.
