← GeographyWhich outcome occurs when increased freshwater stream discharge enters high-latitude seas?
A)Weakening thermohaline circulation✓
B)Intensified coastal upwelling
C)Strengthened sea ice formation
D)Decreased coastal erosion rates
💡 Explanation
Increased freshwater input reduces surface water salinity, therefore decreasing its density; this impedes convective overturning, which is a reduction in the **thermohaline circulation**, because dense, salty water sinks, rather than continuing to circulate.
