← GeographyWhich long-term geomorphic consequence primarily results when isostatic rebound occurs after glacial retreat in fjord regions?
A)Subsidence beneath sediment load
B)Increased sea cliff erosion rates
C)Emergence of elevated shorelines✓
D)Accelerated river delta progradation
💡 Explanation
When glacial ice melts, isostatic rebound occurs because the Earth's crust, previously depressed by the ice mass, slowly rises due to reduced pressure, leading to land uplift. Therefore emergence of elevated shorelines around fjords results, rather than delta progradation, sea cliff erosion, or land subsidence which happen under alternate mechanisms.
