Why do not clouds fall?
One of the obvious questions that any child may think of, but do you have an answer? If you think the reason is that the clouds are composed of water vapor and lighter than air, your answer is wrong! This is because it does not consist of water vapor, but of the water itself. What makes it overcome the forces of gravity and does not fall?
In short, it can be said that the cloud overcomes the Earth's gravity because the forces of cohesion between drops of water are greater than the force of gravity, because the volume of water droplets in the cloud is too small.
Not long ago, the clouds were thought to be made up of small water bubbles filled with water vapor that made them light. This theory is now rejected. The cloud consists of small drops of water ranging in diameter from 0.001 mm to 0.02 mm, and its density is greater than 800 times the air density.
The surface area of these drops plays a prominent role in keeping them suspended in the air. The surface area of these droplets is large for its mass, so when they fall they are subject to great resistance from the air as if they were falling by an umbrella, which means they fall very slowly.
This means that the clouds actually fall, but any stream of light air can lift them and make them hang in the air, and the speed of falling very slow, making it easy to stop.
