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.

• Which factor most increases isostatic rebound rates in fjord regions post-glaciation?
• Which risk increases when seasonal winds reverse direction?
• Which outcome is facilitated by creep along transform faults?
• Which localized effect is caused by adiabatic expansion within a rain shadow region of a mountain range?
• Which process exacerbates desertification when ephemeral streams deposit sediment on alluvial fans?
• Which process primarily drives the global thermohaline circulation when surface water temperature decreases near the poles?
