The natural phenomenon caused by the rotation of the Earth is known as the spireal effect, or more commonly referred to as the Coriolis effect. This effect influences wind patterns and ocean currents, causing moving air and water to turn and twist rather than flow in a straight path. The rotation causes objects in the northern hemisphere to deflect to the right, while in the southern hemisphere, they deflect to the left. This principle is crucial for understanding weather systems, oceanography, and the general movement of the atmosphere, impacting global climate patterns.
