Question

Quizplus · Accepted Answer

The Coriolis effect is a result of the Earth's rotation. This effect causes objects, such as air and water, to appear to curve in their path of motion when viewed from a fixed point on the Earth's surface. The speed and direction of the object, as well as the latitude of the fixed point, also influence the degree of curvature. The Coriolis effect is important in explaining phenomena such as the rotation of storms like hurricanes and the formation of ocean currents.
