Which process limits alluvial plain formation following glacial retreat?

💡 Explanation

Isostatic rebound reduces the local topographic gradient, because decreased water flow reduces erosion, eventually halting plain formation, therefore fluvial deposition favors steeper gradients rather than continued alluvial expansion on flatter terrain.
