← GeographyWhich outcome occurs from increased glacial meltwater streams?
A)Decreased North Atlantic overturning circulation✓
B)Increased global thermohaline circulation rate
C)Strengthened polar front jet stream
D)Weakened subtropical high pressure cells
💡 Explanation
Decreased overturning circulation happens because the influx of freshwater reduces the density of the surface water, slowing down the sinking (North Atlantic Deep Water formation) that drives Thermohaline Circulation; therefore, reduced ocean salinity, rather than increased salinity affects density-driven currents.
