Which outcome typically occurs when glacial retreat exposes a U-shaped valley to marine inundation?

💡 Explanation

Marine inundation of a U-shaped valley due to glacial retreat causes fjord formation because isostatic rebound and sea level rise drive the process, therefore creating a deepwater inlet, rather than a shallow estuary as typically formed by riverine processes.
