← GeographyWhich long-term isostatic process elevates previously submerged fjord landscapes?
A)Glacial rebound following ice sheet melt✓
B)Sea level rise from thermal expansion
C)Tectonic uplift from subduction zones
D)Sediment deposition within fjord basins
💡 Explanation
When glacial ice sheets melt, isostatic rebound occurs because the Earth's crust slowly rises after being depressed by the weight of the ice, elevating fjord landscapes. Therefore, glacial rebound results, rather than sea level rise, tectonic uplift, or sediment deposition which operate through different mechanisms and timescales.
