  2. Calcium carbonate

  3. Sulphur dioxide

  4. Ammonium phosphate
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • An artificial method of rain is called seeding cloud. It is a type of weather modification. 
  • This method aims at to change the amount of precipitation which falls from clouds. The method uses seeding of certain substances into the air that will serve as cloud condensation. 
  • In this, tiny particles like potassium iodide or dry ice are seeded (sprayed) in the atmosphere. 
  • The water present in the air is attracted and condenses near the sprayed particles. 
  • It further crystallises to form ice. Finally, it causes the rainfall. 
  • Thus, the correct answer is option A.
