← GeographyWhich feedback results when glacial meltwater reduces salinity?
A)Slower thermohaline circulation development✓
B)Increased upwelling in polar regions
C)Intensified coastal erosion rates
D)Expanded tropical cyclone formation
💡 Explanation
A reduction in salinity decreases water density, disrupting the driving force `density stratification`. This slows thermohaline circulation because dense water sinking can't occur as readily. Therefore, the circulation weakens, rather than intensifying or promoting upwelling elsewhere.
