← GeographyWhich outcome is driven directly by density-driven subsidence in ocean gyres?
A)Deep ocean water ventilation rates✓
B)Equatorial upwelling fertilization
C)Coastal fog concentration levels
D)Sea ice margin retreat acceleration
💡 Explanation
The density-driven subsidence in ocean gyres reduces pressure, which causes the deep ocean water ventilation rates to decrease because downwelling inhibits the water's vertical movement; therefore, there is less exchange, rather than surface effects like fog concentration.
