Clouds form when air is heated by the sun and rises. As the air climbs it continues to slowly cool until a saturation point is reached and the water droplets condense, forming the cloud. As long as the cloud remains warmer than the air around it (cold air is heavy) the cloud will not actually float, but it will fall so slowly it will appear to be floating in the air.
