Q. Consider the following statements regarding cloud seeding:
1.Silver iodide is the most commonly used substance in cloud-seeding.
2.Stratus clouds are targeted in cloud-seeding to induce rain.
3.It can also help in preventing earthquakes by stabilizing atmospheric pressure.
Which of the statement(s) given above is/are correct?
Answer: B
Notes:
Explanations –
Statement 1 is correct. Silver iodide is one of the most commonly used chemicals for cloud seeding, along with potassium iodide and dry ice (solid carbon dioxide).
Statements 2 and 3 are incorrect. Cloud seeding targets cumulus clouds, which are more conducive to precipitation. Stratus clouds are usually low-lying and less likely to produce significant rainfall through cloud seeding. Cloud seeding is a weather modification technique aimed at inducing precipitation, mitigating hail, or dispersing fog. It has no connection to preventing earthquakes or stabilizing atmospheric pressure.
