Which mechanism causes deflection of trade winds in Northern Hemisphere due to Earth’s motion?

💡 Explanation

When the Earth rotates, the Coriolis effect induces a deflection of air masses because air is moving through space. Due to Earth's curvature, The impact from Coriolis Effect depends on Hemispheres deflecting winds East within the the Northern, while West in Southern regions. Therefore Coriolis drives the circulation, altering the original trajectory, rather than other options which describe completely different effects which do not account for planetary motion.
