Q83. Which of the following regions of India is most prone to earthquakes?
- A. Western Rajasthan
- B. Deccan Plateau
- C. Himalayan Belt
- D. Coastal Plains
Correct Answer: C. Himalayan Belt
Explanation:
The Himalayan region lies along a convergent plate boundary where the Indian Plate collides with the Eurasian Plate, making it highly seismically active.
Q84. Consider the following statements about cyclones in India:
1. Most tropical cyclones affecting India originate in the Bay of Bengal.
2. Cyclones are more frequent during the southwest monsoon season.
3. Eastern coastal states are more vulnerable than western coastal states.
- A. 1 and 2 only
- B. 1 and 3 only
- C. 2 and 3 only
- D. 1, 2 and 3
Correct Answer: B. 1 and 3 only
Explanation:
Bay of Bengal produces more cyclones than the Arabian Sea. Cyclones mainly occur during pre- and post-monsoon periods, not peak monsoon.
Q85. Which one of the following factors increases the intensity of heatwaves in India?
- A. Western disturbances
- B. La Niña conditions
- C. El Niño conditions
- D. Frequent cyclones
Correct Answer: C. El Niño conditions
Explanation:
El Niño suppresses monsoon rainfall and increases temperature extremes, leading to more frequent and intense heatwaves in India.
Q86. Which of the following regions is highly prone to floods due to braided river systems?
- A. Western Ghats
- B. Brahmaputra Valley
- C. Malwa Plateau
- D. Bundelkhand Region
Correct Answer: B. Brahmaputra Valley
Explanation:
The Brahmaputra has a braided channel pattern, high sediment load and heavy monsoon rainfall, making the region extremely flood-prone.
Q87. Which one of the following best explains cloudburst events in India?
- A. Long-duration moderate rainfall
- B. Sudden and intense rainfall over a small area
- C. Snowfall followed by melting
- D. Cyclonic rainfall over coastal areas
Correct Answer: B. Sudden and intense rainfall over a small area
Explanation:
Cloudbursts involve extremely heavy rainfall (usually more than 100 mm/hour) over a localized area, common in Himalayan regions.
Q88. Which of the following disasters is most closely associated with deforestation?
- A. Earthquake
- B. Tsunami
- C. Landslide
- D. Volcanic eruption
Correct Answer: C. Landslide
Explanation:
Deforestation reduces slope stability, increasing susceptibility to landslides, especially in hilly and mountainous regions.
Q89. Which Indian coastal state is most vulnerable to cyclones?
- A. Kerala
- B. Gujarat
- C. Odisha
- D. Maharashtra
Correct Answer: C. Odisha
Explanation:
Odisha’s location along the Bay of Bengal and shallow continental shelf make it highly vulnerable to severe cyclones.
UPSC Disaster Geography Tip:
Always link disasters with location + physical process + human activity.
