← GeographyWhich outcome occurs when equatorial warm air rises, cools, and subsequently deviates as it moves poleward?
A)Development of trade wind patterns✓
B)Formation of polar ice sheets
C)Increased coastal upwelling intensity
D)Intensification of volcanic eruptions
💡 Explanation
Trade wind patterns arise through atmospheric circulation because Coriolis effect deflects the descending air east or west. This deflection generates predictable wind patterns rather than uniformly poleward movement, therefore creating circulating trade winds, rather than ice sheet or volcanic changes.
