← GeographyWhich effect of the Coriolis force is most pronounced on large-scale wind patterns?
A)Deflection creating geostrophic wind✓
B)Increased frictional drag near surface
C)Formation of localized microclimates
D)Suppressed vertical air movement aloft
💡 Explanation
When air masses move across Earth's surface, the Coriolis force deflects them due to Earth's rotation, causing geostrophic wind because the pressure gradient force is balanced by Coriolis. Therefore deflection creating geostrophic wind results, rather than increased friction, microclimate formation, or suppressed vertical movement, which depend on other factors.
