← GeographyWhich pattern results because excessive freshwater reduces gyre density?
A)Weakened ocean overturning circulation✓
B)Increased coastal upwelling intensity
C)Accelerated sea level rise
D)Intensified deep-sea hydrothermal vent activity
💡 Explanation
A large influx of freshwater decreases water density, which drives thermohaline circulation; therefore, ocean overturning weakens, rather than intensifying other ocean processes that rely on density differences because these processes are affected by other factors.
