Towering Summer Cloud
Open to everyone until Tuesday, September 29
To keep it, print it while it is open.
On a hot day, air near the ground warms and rises. High in the sky it cools, and its water turns into a tall dark cloud with a flat bottom.
In the picture
- Shimmering air above the grass: warmed air rises from the ground.
- Dark middle of the towering cloud: rising air has cooled high in the sky.
- Flat base of the cloud: tiny water drops have formed and gathered there.
Examples
- Steam rising from a hot pavement.
- Drops forming on the outside of a cold drink can.
Key takeaways
- Warm air rises.
- Cooling high up turns water vapor into cloud drops.
