← GeographyWhich outcome occurs when the Coriolis effect weakens locally?
A)Decreased gyre circulation strength✓
B)Increased coastal upwelling events
C)Intensified equatorial current divergence
D)Reduced extratropical cyclone frequency
💡 Explanation
A weakening Coriolis effect diminishes the geostrophic balance of oceanic gyres because deflection forces are smaller, therefore, circulation diminishes, rather than intensifying currents or upwelling tied to stronger deflection.
