it cools and eventually condenses, usually on tiny particles of dust in the air. It condenses when it hits the dew point. When it condenses it becomes a liquid again or turns into either ice, hail, rain, sleet or, snow. These water particles eventually come together and form clouds. Precipitation in the form of ice, rain, sleet, snow and hail comes from clouds. Clouds move around the world, propelled by air currents.
