Precipitation descriptions
Question | Answer |
---|---|
How does rain form? | Takes place when drops of liquid water fall all the way to the surface of the Earth. |
How does snow form? | Forms when water vapor turns directly into ice without every passing through a liquid state. This happens as water condenses around an ice crystal. |
How does sleet form? | Refers to a mixture of snow and rain, as well as raindrops that freeze on their way down. Unlike snow, the raindrops pass through a liquid form before freezing. |
How does hail form? | Forms in cumulonimbus clouds as ice crystals begin to fall. Updrafts catch the ice crystals pushing them up into the clouds. As they fall, they continue growing in size. This process may be repeated until the hail stone becomes too heavy and falls. |
drops of water, may never reach the ground in dry areas; varies greatly in size and speed of fall; precipitation that falls throughout most of the world | Rain |
six-sided figures; makes up all precipitation in the inland areas of Antarctica | Snow |
clear, solid grains of ice, smaller than five millimeters in diameter; formed by the freezing of raindrops or refreezing of partially melted snowflakes;makes a rapping sound when hitting a hard surface | Sleet |
ranges in size from a pea to an orange; falls at a speed of about 22 miles per hour; forms in thunderstorm clouds, beginning as frozen raindrops or snow pellets; round, irregularly shapes lumps of ice; falls most often in Wyoming, Nebraska and Colorado | Hail |
