evaporation is when a mass of water is hit by sunlight and some of it turns to a vapor. In the atmosphere, that vapor cools and the water molecules fuse with other water molecules, forming clouds.

In the Northern Hemisphere, for example, predictable winds called trade winds blow from east to west just above the equator. The winds pull surface water with them, creating currents. As these currents flow westward, the Coriolis effect—a force that results from the rotation of the Earth—deflects them. The currents then bend to the right, heading north. At about 30 degrees north latitude, a different set of winds, the westerlies, push the currents back to the east, producing a closed clockwise loop.
