The rotation of earth affects the direction of _________.

  1. Cyclone

  2. Anticyclone

  3. Both a and b

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the absence of rotation, the wind tends to blow from areas of high pressure to areas of low pressure. The stronger the pressure differences between a high-pressure system and a low-pressure system, the stronger the wind. The coriolis force caused by Earth's rotation gives winds within high-pressure systems their clockwise circulation in the northern hemisphere as the wind moves outward and is deflected right from the center of high pressure and anticlockwise circulation in the southern hemisphere as the wind moves outward and is deflected left from the center of high pressure. Friction with land slows down the wind flowing out of high-pressure systems and causes wind to flow more outward from the center.

North-Western parts of India get winter rainfall mainly due to ______.

  1. North-West monsoon

  2. Western disturbances

  3. North-East monsoon

  4. Retreating monsoon
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Western disturbances, specifically the ones in winter, bring moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian Subcontinent. They are the cause of most winter and pre-monsoon season rainfall across northwest India.

  2. symptoms, preparations

  3. disperse, weaken

  4. plan, destruction

The centre of cyclone is called the _________.

  1. Centre of the storm

  2. Eye of the storm

  3. Focus

  4. Radius
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The eye is a region of mostly calm weather at the center of strong tropical cyclones. The eye of a storm is a roughly circular area, typically 30–65 km (20–40 miles) in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather occurs.

Which one among the following conditions is not required for emergence of tropical cyclone?

  1. Peninsular land mass

  2. Strong Coriolis forces

  3. Large and continuous supply of warm and moist air

  4. Absence of strong vertical wind wedge
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tropical cyclones require warm ocean waters, high humidity, and atmospheric instability. A peninsular land mass is not a requirement; in fact, land masses often weaken cyclones by cutting off the moisture supply.

Disaster management covers _________.

  1. Maintaining control over disasters

  2. Reducing the effects of disasters

  3. Briefing the top officials of government on the effects of disasters

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Disaster Management should aim to prevent emergencies from occurring, and failing that, should develop a good action plan to mitigate the results and effects of any emergencies. The development of emergency plans is a cyclical process, common to many risk management disciplines are set out below:

  1. Recognition or identification of risks
  2. Ranking or evaluation of risks
  3. Maintaining control over disasters
  4. Responding to significant risks
  5. Resourcing controls
  6. Reducing the effects of disasters
  7. Reaction planning
  8. Briefing the top officials of government on the effect of disasters
  9. Reviewing the Risk Management framework

  1. Cloudy and highly stormy

  2. Full of strong winds

  3. Calm and cloudless

  4. Site with high atmospheric pressure
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The eye of a cyclone is the central region of the storm, characterized by low pressure, light winds, and clear or calm skies, surrounded by the eyewall where the most intense weather occurs.

What does the acronym ISDR stand for?

  1. International Strategy for Disaster Reduction

  2. International Significant Disaster Resources

  3. International Sustainable Development Report

  4. Intergovernmental Strategy for Developing Recreation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The International Strategy for Disaster Reduction (ISDR) is a global framework established within the United Nations for the promotion of action to reduce social vulnerability and risks of natural hazards and related technological and environmental disasters.

Its main purpose is to facilitate, in an inter-agency effort Governments and communities in disaster-prone areas in integrating the management of risk into their development policies, programs and projects.
