Which process causes increased sedimentation rates near the mouths of fjord estuaries following glacial retreat?

💡 Explanation

When glacial retreat exposes unstable fjord walls, solifluction occurs because thawed surface soil flows downslope, increasing erosion and sediment input into the fjord. Therefore increased sedimentation results, rather than isostatic changes, flocculation, or thermokarst, which are independent mechanisms with differing triggers.
