Which consequence results when freeze-thaw cycles saturate soil?

💡 Explanation

Increased pore water pressure reduces soil shear, triggering solifluction, the gradual downhill movement of saturated soil, because material flows more easily. Therefore, solifluction rate increases rather than causing reduced river base level in the wider drainage basin.
