Water droplets may freeze to form ice
- If a cloud is colder, like it would be at higher altitudes, the water droplets may freeze to form ice. These ice crystals then fall to the earth as snow, hail, or rain, depending on the temperature within the cloud and at Earth’s surface.

Why do water droplets form in warm air?
When air cools down the water vapour condenses from a gas into a liquid and forms tiny water droplets. Water droplets gather to form clouds. The water droplets get bigger and heavier. The...
the rain is lighter because the warm air advances and rises over the cold air. Frontal rain occurs mainly in mid-latitude regions where warm tropical air meets cold polar air.
Sep 11, 2024 · Falling snow encounters, first a layer of warmer air, which melts the snowflakes, and then, just above the surface of Earth, a very cold layer, which makes the liquid water “super-cooled,” ready to freeze up at the slightest hint of encouragement.
The cooler air stays where it is, and lies underneath the warmer air. 3) As the warmer air rises over the cold air it starts to cool. 4) As the air cools, water vapour is precipitated and the cloud forming process begins, leading to rain. Sky's are typically grey and cloud covers almost all the sky.
- Phantom rain. Under certain conditions, rain can fall from the sky without ever reaching the ground. It happens when rain falling from a cloud evaporates or sublimes as it approaches the earth's surface.
- Is it better to walk or run in the rain? Perhaps you've been caught in the rain and wondered if its better to run as fast as you can to get out of the rain, or whether running into the rain will make you wetter than walking?
- Rain has a smell. When raindrops fall on dusty or clay soils, they trap tiny air bubbles on the surface which then shoot upward - as in a glass of Champagne - and burst out of the drop throwing aerosols of scent into the air where they are then distributed by wind.
- Shape of a raindrop. While raindrops are usually represented in the shape of a teardrop, in reality they are not. When they first form high up in the atmosphere, they form a spherical shape as the water molecules bind together held by surface tension.
Sep 30, 2021 · Rain doesn't come down from clouds by magic – instead, it's part of the precipitation cycle, which is how water moves from its liquid form on Earth to its gas or vapor form in the atmosphere, and then back again. Clouds form as water evaporates and rises, and rain happens as that rising air cools.
If you've ever noticed moisture beads on the windows of a warm car on a cold day, you've seen condensation in action. Warm air vapor touches the cold window and the vapor turns back to a liquid. Clouds form along similar lines.
