← GeographyWhich mechanism causes the Coriolis effect to deflect ocean currents strongest near the poles?
A)Increased water density gradient
B)Greater latitudinal change per distance✓
C)Enhanced wind shear near ice
D)Reduced gravitational force variability
💡 Explanation
When moving across the Earth's surface, objects are deflected due to the Earth's rotation because the Coriolis effect is proportional to the sine of latitude; the change in latitude per unit distance is greatest near the poles, making deflection stronger. Therefore greater latitudinal change results, rather than wind shear which is secondary factor.
