← GeographyWhich outcome occurs when freshwater influx disrupts circulation?
A)Deep water formation rate decreases✓
B)Global current system stabilizes rapidly
C)Coastal upwelling zones unexpectedly intensify
D)Oceanic salinity becomes globally uniform
💡 Explanation
A decline in freshwater density reduces deep water formation because density differences drive thermohaline circulation; therefore, stratification increases and deep water formation lowers, rather than increased upwelling or stabilization which require dense sinking water.
