Clouds form when water vapor in the atmosphere cools to

Clouds form when rising air, through expansion, cools to the point where some of the water vapor molecules "clump together" faster than they are torn apart by their thermal energy.

Clouds are formed when moist, warm air rises and expands in the atmosphere. The rising water vapor condenses and forms small water droplets which make up the clouds. When the water vapor cools, the low temperature of air lowers its capacity to hold water vapor.

HOPE THIS HELPS AND GOOD LUCK
