← GeographyWhich outcome occurs when Earth's rotation speed increases, affecting Hadley cell circulation?
A)Narrower Hadley cells and stronger trade winds✓
B)Weaker jet streams and diffused rainfall
C)Expansion of deserts away from tropics
D)Polar cell intensification and cooling trends
💡 Explanation
Increasing Earth’s rotational speed enhances the Coriolis effect, therefore leading to stronger deflection of air masses and the formation of narrower Hadley cells and amplified trade winds, because the deflection is more pronounced, rather than diffused rainfall or shifts in the deserts location.
