Ice Crystals That Melt on the Way Down
Open to everyone until Friday, October 2
To keep it, print it while it is open.
High in a cold cloud, water freezes into little ice stars. If the air lower down is warm enough, they melt into round raindrops before they land.
In the picture
- A six-armed ice crystal: frozen water in the cold air near the cloud
- A band of warmer air: the layer that melts the falling ice
- A round droplet: melted water that lands as rain
Examples
- Snow falling on a cold mountain top
- Sleet tapping the window on a chilly morning
Key takeaways
- The same cloud can make snow or rain, depending on how warm the air below is.
- Ice crystals melt into round droplets when they fall through air above freezing.
