What is used to produce artificial rain ?

  • A.copper oxide
  • B.carbon monoxide
  • C.silver iodide
  • D.silver nitrate

Answer: C

Silver iodide is used to produce artificial rain.

Its crystal lattice closely resembles that of ice, so supercooled droplets in a cloud freeze on it and grow heavy enough to fall. It is dispersed from aircraft or fired from the ground into a cloud that already holds enough moisture.
