← GeographyWhich global outcome occurs when tropical sea surface temperatures increase?
A)Intensified Hadley cell convection✓
B)Weakened thermohaline circulation
C)Decreased coastal upwelling
D)Reduced precipitation in arid regions
💡 Explanation
Increased sea surface temperatures cause enhanced evaporation and rising air in the tropics; this strengthens Hadley cell convection because warmer air holds more moisture. Therefore, stronger circulation is the outcome, rather than changes to thermohaline circulation.
