Precipitation

 

     When water falls to Earth, it is called precipitation. Rain, snow, sleet, and hail are all forms of precipitation. For rain to fall, the water drops in a cloud must reach a certain size. as the tiny droplets of water in a cloud bumb into each other, they combine. When the drops are heavy enough, they fall as rain.

 

 

 

     If the air is very cold, water vapor in a cloud may freeze into tiny ice crystals called snow. All snowflakes have six sides, or points. If rains falls through a layer of very cold air before reaching the ground, the drops will freeze. They form pieces of ice called sleet. Sleet forms only in cold weather.
