Which process primarily influences the stability of fjord slopes following glacial retreat, potentially leading to landslides?

💡 Explanation

When glaciers retreat from fjords, isostatic rebound occurs because the land slowly rises due to the removal of the ice load, and the simultaneous rapid accumulation of sediments destabilizes slopes, increasing landslide risk. Therefore isostatic rebound and sediment loading are critical, rather than weathering, uplift, or erosion which operate over longer timescales or require different geological conditions.
