← GeographyWhich outcome results from thermal expansion differences in ocean currents?
A)Thermohaline vertical water mass segregation✓
B)Depletion of benthic nutrient concentration
C)Strengthened coastal upwelling events offshore
D)Reduction in ocean's carbon dioxide uptake
💡 Explanation
Thermohaline circulation depends on density differences; differential thermal expansion causes density variations segregated by depth because colder, saltier water sinks, leading to vertical stratification rather than impacting coastal upwelling, nutrient concentration, or carbon uptake.
