What is a cloud
What is a cloud?

Before learning about cloud seeding, we must know what a cloud is.
As you know, there are three states of matter solid, liquid and gas. Water is made up of these three states.
Ice which is solid
Water is a liquid
Water vapor is gas.
And if something converts from one state of matter to another, that process contains a name. For example, when ice turns into water this process is called melting. When water turns into ice it is called freezing. And when water turns into vapors it is called evaporation. And when water vapor turns into water, it is known as condensation.
As you know the higher, we go the colder it gets. Like mountains are so cold and when water vapor rises in at a higher altitude, due to cold it condenses and then those water vapors convert into water and becomes small droplets of water. And when these water droplets are suspended in the air, we see clouds. These are clouds. The water droplets which make up a cloud are very small; these are almost a one hundredth part of a millimeter (1/100) and there are millions of water droplets in a cloud. And when a cloud is at more altitude it becomes colder, it means that freezing also happens in this process and then these droplets convert into ice crystals that form the cloud. So, in this sense there are two types of a cloud:
One is made up of water droplets and the other one is made up of ice crystals.
After we have understood this, how is a cloud made? Then the next question is:
How do these clouds rain?

The small water droplets, when they keep collecting; many more droplets join them and the cloud gets bigger and bigger than those small droplets start colliding with each other; they start mixing and make big droplets then these big droplets go up and freeze, forming ice crystals and the ice crystals also start colliding with each other, then they make more bigger ice crystals this process continues until the ice crystals become so big that they start falling because of their weight. While they fall, if the air temperature is warm, they will fall like rain (in the form of water) and if the temperature of air is cold, they will fall like snow and snowfall will happen.
