← GeographyWhich mechanism causes deflection of ocean gyres formed along continental eastern boundaries?
A)Coriolis effect influencing trajectory✓
B)Density gradients caused by salinity
C)Thermocline depth affecting upwelling
D)Wind shear force due to landmasses
💡 Explanation
When ocean gyres move, the Coriolis effect influences a force perpendicular to the gyre's movement because Earth's rotation affects moving objects. Therefore, the current is deflected eastward in the Northern Hemisphere and West in the Southern Hemisphere, rather than density, thermocline, or landmass influences.
