A cloud forms in the sky. It is a collection of water or ice that we can see with our eyes.
This is how a cloud is made: The sun heats the air. If the air cools down below the dew point (32°F or 0°C), the air then fills with water drops. A cloud is formed!
There are four groups of clouds:
1. nimbus
2. stratus
3. cumulus
4. cirrus
Each group of clouds has four families.
1. cirro
2. alto
3. strato
4. fog
