Explanation
The correct answer is density because clouds are composed of tiny water droplets or ice crystals that are extremely small and light. These particles have a very low terminal velocity and are surrounded by air. Because the overall mass of these droplets is spread over a large volume, the effective density of a cloud is very low. Additionally, upward atmospheric currents and the buoyancy of warmer air counteract the force of gravity, allowing these low density formations to remain suspended in the atmosphere rather than falling immediately to the ground.
