Why do very tiny cloud droplets not fall immediately?

Answer and explanation

Correct answer: They are light and can remain suspended in air

Correct answer: A. Very small cloud droplets have little mass, so their downward gravitational effect is weak compared with the support and turbulence of surrounding air. Upward air currents can keep them suspended, and air resistance also strongly affects their motion. Inside a cloud, droplets may collide and combine, or grow through other cloud processes. As they become larger, their weight increases and they can fall as precipitation when downward motion overcomes the supporting effects of air. The droplets do not become stones, so B is absurd. They do not push Earth, so C is incorrect. They do not always become fire, so D is scientifically false. Memory cue: tiny droplets float; growing droplets fall.
