GEOLOGY

Detailed explanation-1: -The most common chemicals used for cloud seeding include silver iodide, potassium iodide and dry ice (solid carbon dioxide). Liquid propane, which expands into a gas, has also been used. This can produce ice crystals at higher temperatures than silver iodide.

Detailed explanation-2: -When storm systems move through one of our cloud seeding project areas, a solution containing a small amount of silver iodide is burned from ground-based generators or released from aircraft. Upon reaching the cloud, the silver iodide acts as an ice forming nuclei to aid in the production of snowflakes.

Detailed explanation-3: -This can be done with the help of certain chemicals that are similar to ice such as dry ice or solid carbon dioxide, potassium iodide, silver iodide etc.

Detailed explanation-4: -Cloud seeding is the process where substances like dry ice and silver iodide are put into clouds in an attempt to make precipitation fall. Cloud seeding has also been used to dissipate fog and weaken some storms.
