This is Rain, Rain is liquid water in the form of water droplets that have condensed from atmospheric water vapor and then precipitated—that is, become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation.
Sleet, precipitation of small, partially melted grains of ice. As raindrops fall from clouds, then they pass through layers of air at different temperatures. If they pass through a layer with a temperature below the freezing point, they turn into sleet. Sleet falls as tiny, hard pieces of ice. Sleet usually cannot do severe damage to crops or transportation systems the way heavy snow, freezing rain, or hail can. In fact, sleet is so light and tiny it usually bounces when it hits a hard, hard surface.
