Which 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.
