← GeographyWhich consequence results when increased freshwater influx disrupts North Atlantic gyres?
A)Enhanced coastal upwelling intensity
B)Accelerated thermohaline circulation rate
C)Weakened Gulf Stream current intensity✓
D)Increased equatorial CO2 absorption
💡 Explanation
A large freshwater influx reduces surface water density and impedes sinking, which disrupts the gyre cycle via density driven sinking cessation. This weakens the Gulf Stream, because the thermohaline circulation mechanism slows, therefore weakens the current, rather than accelerate it or enhances upwelling which involves wind.
