← GeographyWhich effect contributes to deepwater formation near Antarctica?
A)Brine exclusion increases water density✓
B)Rapid evaporation decreases salinity locally
C)Algal blooms absorb surface nutrients
D)Submarine volcanic activity warms water
💡 Explanation
When sea ice forms, salt is excluded; this brine rejection greatly increases the surrounding water's density, initiating thermohaline circulation. Brine exclusion drives density, because density increases rather than decreased salinity from evaporation or different thermal effects.
