← GeographyWhich atmospheric effect results when a strong pressure gradient forces air towards the poles within a Hadley cell?
A)Development of subtropical desert regions
B)Formation of intense low-pressure cyclones
C)Deflection of geostrophic winds by Coriolis✓
D)Weakening of the intertropical convergence zone
💡 Explanation
When air masses move poleward due to pressure gradients in a Hadley cell, the Coriolis effect deflects them because Earth's rotation causes moving objects to veer right in the Northern Hemisphere and left in the Southern Hemisphere. Therefore, geostrophic winds are deflected, rather than deserts, cyclones, or weakening because these require different atmospheric mechanisms.
