What is cloud seeding?
Cloud seeding is the process of spreading either dry ice, or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain.
Since most rainfall starts through the growth of ice crystals from super-cooled cloud droplets (droplets colder than the freezing point, 32 deg. F or 0 deg. C) in the upper parts of clouds, the silver iodide particles are meant to encourage the growth of new ice particles.
The history of cloud seeding has experienced uncertain results because it can never be known whether a cloud that rains after seeding might have rained anyway. This is because seeding is performed on clouds that look like they have some potential for producing rain.

The crystalline structure of β-AgI is similar to that of ice, allowing it to induce freezing by the process known as heterogeneous nucleation. Approximately 50,000 kg are used for cloud seeding annually, each seeding experiment consuming 10-50 grams.
It could be any number of chemicals, including salt. Silver iodide is just one type.

so you are saying those lines in the sky
are silver iodide sprayed by planes?

i like option no. 4........population control. He who controls the weather, makes the rules! It would be a "conspiracy" if there weren't actual facts to support their projects. They have been quite successful, at weather modification. I can think of 3 instances, to support that claim!
In physics, a charged particle is a particle with an electric charge. It may be either a subatomic particle or an ion. A collection of charged particles, or even a gas containing a proportion of charged particles, is called a plasma, which is called the fourth state of matter because its properties are quite different from solids, liquids and gases (plasma is the most common state of matter in the universe). Particles either have a positive, negative or no charge (being neutral).
Silver iodide is prepared by reaction of an iodide solution (e.g., potassium iodide) with a solution of silver ions (e.g., silver nitrate).

In chemistry, salts are ionic compounds that can result from the neutralization reaction of an acid and a base. They are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge).

Here, let me try to help you because you are SERIOUSLY CONFUSED!

50,000 kilograms, is 50,000 kilograms too much! Does it matter if you shoot a person with a .45 or a rifle?
