Question | Answer |
What is rain? | water droplets that are at least 0.5 mm in diameter |
What is the most common type of precipitation? | rain |
What are smaller drops of rain called? | drizzle |
What are droplets that are even smaller than drizzle called? | mist |
What type of clouds do drizzle and mist usually fall from? | stratus clouds |
What is sleet? | begins as a water droplet in the clouds, but falls through a layer of air that is below 0° C/32° F; as it falls it freezes into a solid particle of ice; must be smaller than 5 mm in diameter |
What is hail? | Round pellets of ice larger than 5 mm in diameter |
When does hail occur? | during thunderstorms |
What type of clouds does hail form in? | cumulonimbus clouds |
How does hail form? | starts as an ice pellet inside a cold region of a cloud, winds moving upward carry the pellet up through the cold region of the cloud many times & a new layer of ice forms around it until it becomes too heavy for the wind to lift & it falls to the ground |
How does snow form? | when water vapor condenses into an ice crystal rather than a water droplet and falls as snow as long as the air from the cloud to the ground is at or below 0° C/32° F |
How is powdery snow formed? | when snow falls through cold, dry air |
In what conditions do snowflakes tend to clump together and form larger flakes? | when the air falls through humid air that is close to freezing |
How does freezing rain form? | when liquid water droplets fall to Earth’s surface as liquid, but freeze when they touch a surface whose temperature is at or below 0° C/32° F |
