Water vapour condenses to form tiny water droplets which appear as clouds. Why don't these water droplets fall to the earth immediately after condensing? What keeps them floating in the sky for so long?

Solution

In clouds most of the condensed water does not fall as precipitation because their falling speed is less and not able to overcome clouds updraft speed. When water droplets grow due to additional condensation, the particles collide. On achieving enough collisions to produce a droplet with a falling speed which exceeds the cloud updraft speed, then precipitation of cloud occur as rain.
