← GeographyWhich resulting phenomenon directly strengthens currents due to thermohaline circulation?
A)Polar region sea ice formation✓
B)Equatorial solar irradiance decline
C)Upper-atmosphere CO₂ concentration decrease
D)Reduction of continental glacial mass
💡 Explanation
Sea ice formation, by excluding salt from water, increases the density causing sinking; this accelerates thermohaline circulation because density differences drive it downward, therefore strengthening currents, rather than decreased irradiance, upper-atmosphere CO₂ or reduced glacial mass.
