← GeographyWhich of these outcomes arises when thermohaline circulation weakens?
A)Altered air temperature pressure gradients✓
B)Increased deep ocean vent activity
C)Decreased rate of glacial ablation
D)Rapid exosphere ice crystal formation
💡 Explanation
A weakened thermohaline circulation alters global heat distribution, affecting air temperature and pressure gradients globally due to heat transport reduction, therefore changing prevailing cell circulation intensities rather than influencing geochemical systems because deep-sea vent activity has other drives.
