← GeographyWhich outcome occurs when increased glacial meltwater streams significantly freshen North Atlantic surface waters?
A)Reduced North Atlantic Deep Water formation✓
B)Strengthened thermohaline current upwelling
C)Increased El Niño Southern Oscillation events
D)Accelerated global sea level decrease
💡 Explanation
Reduced salinity decreases water density, which reduces the rate of the North Atlantic Deep Water formation because density-driven *thermohaline circulation* is impeded; therefore, North Atlantic Deep Water formation is reduced, rather than upwelling increased, which requires denser water.
