← GeographyWhich salinity outcome follows decreased polar ice formation?
A)Weaker North Atlantic gyre circulation✓
B)Stronger equatorial upwelling dynamics
C)Increased thermocline layer stability
D)Intensified Antarctic bottom water formation
💡 Explanation
Reduced ice formation leads to a decrease in dense, cold water because brine rejection weakens the thermohaline circulation, reducing the North Atlantic gyre; therefore, ocean currents slow rather than intensify. Upwelling/thermocline stability depend on separate factors.
