Which process most directly shapes the long profile depth of a fjord's underwater topography after glacial retreat?

💡 Explanation

When glaciers retreat from fjords, previously scoured basins become pathways for sediment deposition by turbidity currents, because the sediment laden flows preferentially move down the steep underwater slopes. Therefore A results, rather than B, C, or D which have minimal impact on sculpting underwater fjords.

• Which outcome occurs during a volcanic eruption where pyroclastic density currents encounter a body of water?
• Which flow behavior arises when a meandering stream encounters a sudden decrease in channel slope?
• Which outcome occurs when tectonic uplift interrupts stream thalweg?
• Which process shapes the islands due to wave refraction?
• Which mechanism causes higher methane flux from fjord sediments following glacial retreat?
• Which outcome arises because of continental-scale thermal differences intersecting planetary rotation?
