← GeographyWhich outcome is amplified within fjords during sea-level rise?
A)Stratified water degradation increases sharply✓
B)Deeper water mass oxygenation decreases minimally
C)Circulation patterns promote uniform mixing
D)Shallower sills amplify surface ventilation
💡 Explanation
Sea-level rise causes saltwater intrusion, driving saltwater wedge penetration; this promotes water column stratification because decreased mixing leads to anoxic conditions amplified in fjord basins. Therefore, water stagnation occurs, rather than nutrient mixing or vertical distribution of oxygen.
