← GeographyWhich mechanism explains why major river systems in the Northern Hemisphere deflect to the right?
A)Hydraulic head pressure differential
B)Erosion patterns influencing channel shifts
C)Coriolis effect inducing streamline deviation✓
D)Regional precipitation gradient imbalances
💡 Explanation
Because of Earth's rotation, the Coriolis effect causes moving objects to deflect to the right in the Northern Hemisphere which includes flowing water in river systems. Therefore, river deflection results from Coriolis, rather than hydraulic head, erosion, precipitation gradients needing alternate drivers.
