← GeographyWhich process dominates when increased glacial meltwater dilutes North Atlantic Ocean streams?
A)Thermohaline circulation slow-down✓
B)Subtropical gyre intensification
C)Equatorial upwelling acceleration
D)Coastal erosion rate reduction
💡 Explanation
When glacial meltwater dilutes North Atlantic streams, thermohaline circulation slow-down occurs because decreased salinity reduces water density inhibiting sinking. Therefore circulation weakens, rather than intensification, acceleration, or reduction, which require different oceanic forcing mechanisms related to wind and coastline.
