Clouds are made of liquid water –The water is in very small drops –Some of these collide and combine to form larger drops –The cloud becomes thicker and grayer. –Soon the drops are too heavy for the wind to keep them in the air. –They fall to the ground as precipitation.
raindrops When air temperature is warm; water vapor forms liquid precipitation, or raindrops.
Solid precipitation When the air temperature is below the freezing point of water, water vapor forms solid precipitation. –Sleet –Hail –Snow
Sleet When raindrops fall through a layer of very cold air near the ground, they freeze, changing into tiny bits of ice called SLEET.
Hail Hail can form in severe thunderstorm clouds when raindrops in the cloud collide with bits of ice. The drops freeze, forming hailstones. Wind will then push the hailstones back up into the cloud and the hailstones grow larger. Softball size
