B Correct answer
Explanation

Flood warnings should provide information on what the threat is, what action should be taken, by whom and when. While it is desirable for flood warnings to be accurate, warnings are predictions about the future, so there is inevitably some uncertainty. Accuracy needs to be balanced with timeliness, to allow enough time for appropriate action. Warnings are most likely to reach different audiences and to be heeded if they come from multiple trusted sources.

Which natural calamity has affected India the most?

  1. Floods

  2. Earthquakes

  3. Cyclones

  4. Tsunamis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Of the given options, the destruction caused by cyclones has affected India the most. They mostly strike the eastern coast of India. Recently, the frequency of the tropical cyclones which hit the eastern coast of India has risen. It can be attributed to Global Warming.
Trees, buildings etc collapse due to strong wind killing many people.
Storm surges are Strong winds push water towards a shore. The low-pressure area in the eye lifts the water surface in the center which as high as 3 to 12 m. It appears like a water wall moving towards a shore. As a result, water enters the low coastal areas and causes severe loss of life and property.
Cyclones may also cause prolonged heavy rains. This may lead to floods causing heavy losses. Water becomes contaminated and people may suffer from various water-borne diseases.
It may block the rail and road transport system as well as telephones and other communication systems.
