← GeographyWhich process initiates thermohaline circulation slowdown during Arctic freshwater lens expansion?
A)Reduced surface water density contrasts✓
B)Increased deepwater formation rates
C)Enhanced equatorial upwelling intensity
D)Decreased sea ice brine rejection volume
💡 Explanation
Weakened thermohaline circulation results when freshwater lenses expand, because increased surface freshwater reduces Density Stratification, therefore suppressing convective overturning and deep water formation, rather than increased upwelling or brine rejection changes.
