•A current is the steady flow of a fluid (such as air or water) within a larger body of that fluid.•Prevailing winds are air currents that blow mainly in one direction. The global pattern of prevailing winds is caused by the uneven heating of Earth’s surface. •As prevailing winds blow across the ocean, they create surface currents in the water. Both prev…•Surface currents connect to form large, rotating systems called gyres. Gyres circulate heat around Earth by moving warm water from the equator to the poles.
