← GeographyWhich outcome occurs when increased glacial melt impacts gyre formation?
A)Reduced thermohaline driven water sinking✓
B)Increased coastal upwelling intensity
C)Enhanced deep ocean layer mixing
D)Expanded equatorial current divergence
💡 Explanation
Reduced salinity slows the ocean's thermohaline circulation because decreased density inhibits surface water sinking, a key component of the current. Therefore, the THC weakens, rather than intensifying mixing; upwelling is largely wind-driven.
