Which outcome occurs when increased glacial meltwater enters ocean currents?

A)Weakened thermohaline circulation
B)Increased surface water salinity
C)Strengthened equatorial upwelling
D)Enhanced coastal erosion rates

💡 Explanation

Weakened thermohaline circulation arises from decreased water density because freshwater input reduces ocean salinity, thereby mitigating density-driven sinking; therefore, the current weakens, rather than being strengthened by density differentials or impacting other processes.
