← GeographyWhich outcome occurs when glacial melt increases substantially?
A)Thermohaline circulation weakens considerably✓
B)Coastal upwelling events intensify
C)Oceanic gyre formations accelerate
D)Submarine volcanism incidence declines
💡 Explanation
Increased glacial melt introduces freshwater, diluting ocean salinity and decreasing water density; therefore thermohaline circulation slows because 'density stratification' reduces vertical mixing, rather than upwelling intensification, which requires stronger winds.
