Which effect causes deflections of the atmosphere and oceans due to the rotation of the Earth?

Explanation:
The Coriolis Effect explains the deflection of moving air and ocean waters caused by Earth's rotation. As air and water try to move straight from high to low pressure, the planet’s spin causes them to bend: to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This curvature shapes large-scale wind patterns and ocean currents, influencing weather and climate. Winds describe the motion itself, fronts are boundaries between air masses, and climate refers to long-term patterns—none of these alone account for the rotation-driven deflection that the Coriolis Effect describes.
