← GeographyWhich effect explains deflection of trade winds due to the Earth's spin?
A)Hadley Cell circulation effect
B)Coriolis force deflection effect✓
C)ITCZ convergence zone effect
D)Ekman spiral transport effect
💡 Explanation
When moving across a rotating frame, the Coriolis force deflects wind because the earth's rotation changes the observed trajectory relative to a non-rotating frame. Therefore, the Coriolis deflection force results rather than Hadley cell, ITCZ, or Ekman spiral effects which involve different atmospheric and oceanic mechanisms.
