← GeographyWhich mechanism causes the characteristic curving path of prevailing winds?
A)Coriolis effect deflecting moving air masses✓
B)Thermal expansion pushing air uphill
C)Gravitational gradients pulling air downward
D)Electromagnetic repulsion altering trajectory
💡 Explanation
When global winds move across the Earth's surface, the Coriolis effect deflects these moving air masses at different intensities in the different hemispheres because of the Earth's rotation creating a spin. Therefore, characteristic curving paths manifest, rather thermal lift, gravity, or electromagnetism which do not meaningfully influence trajectories.
