← GeographyWhich outcome results when increased Antarctic ice shelf melting increases stratification?
A)Reduced North Atlantic Deep Water formation✓
B)Increased global thermohaline circulation rate
C)Enhanced upwelling of nutrient-rich water
D)Weakened El Niño Southern Oscillation effect
💡 Explanation
Reduced North Atlantic Deep Water formation results due to decreased density because increased stratification reduces vertical mixing via the haline forcing mechanism; therefore, less dense surface water prevents sinking, rather than promoting it, therefore disrupting the thermohaline circulation.
