Which mechanism intensifies coastal erosion rates along fjord shorelines during regional isostatic rebound?

💡 Explanation

When isostatic rebound occurs, sediment supply is limited because uplifted land exposes bedrock, impeding sediment transport to fjords via rivers and glaciers, thus intensifying erosion. Therefore, supply limitations result, rather than changed wave action, colonization rates, or base level changes, mechanisms that don't directly relate to isostatic uplift/sediment dynamics.

• Reduced river sediment load increases which effect via karst?
• Which mechanism explains how mountain ranges enhance precipitation in the windward slopes, creating rain shadow effects?
• Which outcome will accelerate glacial retreat when volcanic ash deposits darken ice surfaces?
• Which mechanism causes island arc formation during subduction of an oceanic plate beneath another oceanic plate?
• Which climatic effect results when thermohaline circulation weakens due to increased freshwater input in North Atlantic?
