The term for the effect of Earth's rotation on the direction of winds is the Cor/i/o/llis effect. This phenomenon causes moving air and water to turn and twist rather than move in a straight path, influencing weather patterns and ocean currents. In the Northern Hemisphere, for example, winds are deflected to the right, while in the Southern Hemisphere, they are deflected to the left. Understanding the Coriolis effect is essential for meteorology and navigation.
