How precipitation forms cloudsHow precipitation forms clouds
Clouds form when humid air rises upward. Clouds form when humid air rises upward. As the air rises it expands. The further the As the air rises it expands. The further the air molecules rise into the atmosphere the air molecules rise into the atmosphere the cooler they become.cooler they become.
Water droplets or vapor depositions (turns to Water droplets or vapor depositions (turns to crystals) forming clouds.crystals) forming clouds.
Water vapor that cools closer to the ground Water vapor that cools closer to the ground has reached its dew point temperature and has reached its dew point temperature and becomes fog.becomes fog.
