Which erosional consequence results when glacial retreat accelerates within a fjord environment containing submerged bedrock ledges?

💡 Explanation

When glacial retreat accelerates over submerged ledges, enhanced plucking occurs because increased water access at weaknesses allows freeze-thaw action to detach and erode larger rock blocks, steepening the fjord walls. Therefore, the production of steeper fjord walls occurs, rather than excessive rock flour creation or moraine formation, requiring less constrained glacial flow.
