Which outcome develops from increased freshwater runoff inhibiting North Atlantic circulation?

A)Weakened Atlantic Meridional Overturning Circulation
B)Intensified coastal upwelling near Peru
C)Increased global average sea salinity
D)Strengthened Antarctic Bottom Water formation

💡 Explanation

Weakened AMOC results caused by increased freshwater due to reduced density which hinders the sinking aspect of thermohaline circulation, because density differences drive the currents; therefore AMOC is weaker rather than upwelling because this mechanism links to high latitudes.
