The natural phenomenon caused by the Earth's rotation is known as the Coriolis effect. This effect influences the direction of winds and ocean currents, causing moving air and water to turn and twist rather than moving in a straight line. Specifically, in the Northern Hemisphere, the Coriolis effect results in winds and currents curving to the right, while in the Southern Hemisphere, they curve to the left. This phenomenon is crucial in meteorology, as it significantly impacts weather patterns, ocean circulation, and the formation of cyclones and anticyclones.
