The correct option is A a) Silver Iodide.
Ans78. A
Explanation: Cloud seeding is a form of weather modification, is a way of changing the amount or type of precipitation that falls from clouds How? by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud
Chemicals used: In cloud seeding, either dry ice, or more commonly, silver iodide aerosols are sprayed into the upper part of clouds to try to stimulate the precipitation process and form rain
Mechanism: 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.
