What phenomenon explains why objects in motion turn due to the Earth’s rotation?

The phenomenon that explains why objects in motion turn due to the Earth's rotation is known as the Coriolis Effect. This effect arises from the rotation of the Earth on its axis, causing moving objects—such as air masses or ocean currents—to deviate from a straight path. In the Northern Hemisphere, this deflection occurs to the right of the direction of motion, while in the Southern Hemisphere, it occurs to the left.

The Coriolis Effect is a critical consideration in meteorology, influencing wind patterns, ocean currents, and the development of weather systems. For instance, it plays a vital role in the rotation of cyclones, where air is drawn into low-pressure areas. Understanding this effect is essential for interpreting weather data and predicting storm paths.

Other options do not provide an appropriate explanation for this specific motion due to Earth’s rotation. For instance, the Gradient Wind relates to the balance of forces acting on air, La Niña represents a periodic climate pattern, and the Bermuda Triangle is associated with myths and legends, which do not pertain to the scientific principles governing motion affected by Earth's rotation.
