Which process predominantly shapes the bathymetry of a fjord immediately after deglaciation?

💡 Explanation

When glaciers retreat from a fjord, substantial sedimentation from glacial meltwater occurs from the unloading of sediment stored in/on the glacier which flows into the fjord. Therefore sedimentation results, rather than isostatic rebound (slow), marine erosion (relatively slow), or tectonic uplift (extremely slow generally).
