← GeographyWhich outcome occurs when glacial meltwater streams alter density stratification?
A)Reduced deep water formation rate✓
B)Increased coastal mangrove growth rate
C)Strengthened ocean thermohaline circulation
D)Accelerated marine oxygen production rate
💡 Explanation
Reduced deep water formation occurs because freshwater influx decreases surface water density, inhibiting the sinking that drives thermohaline circulation. This suppression of *density-driven circulation* causes slower overturn, therefore reducing the formation rate, rather than increasing circulation which requires density differences to be amplified.
