C. 2, 3 and 4 only
D. 1, 2, 3 and 4
Answer: D
Explanation: Underwater construction can generate noise and vibration, alter sediment dynamics, increase turbidity and disturb aquatic habitats. Such changes can affect the movement, communication, feeding and behaviour of aquatic species, including river dolphins.
Topic 3: Extreme El Niño 2026–27
Q9. With reference to El Niño, consider the following statements:
- It involves abnormal warming of the central and/or eastern equatorial Pacific Ocean.
- It is associated with changes in the Walker circulation.
- Every El Niño event necessarily causes drought across the whole of India.
- It can influence global rainfall and temperature patterns.
Which of the statements given above are correct?
A. 1, 2 and 4 only
B. 1 and 3 only
C. 2 and 3 only
D. 1, 2, 3 and 4
Answer: A
Explanation: El Niño involves abnormal warming of the tropical Pacific and associated atmospheric circulation changes. It can influence weather patterns globally. However, its effect on India is not deterministic and does not necessarily produce drought across the entire country. NOAA’s current assessment indicates a very strong 2026–27 event is highly probable.
Q10. Consider the following statements regarding El Niño and the Indian monsoon:
- El Niño generally tends to weaken the Indian summer monsoon.
- Its impact on the Indian monsoon can be modified by other climate phenomena.
- A positive Indian Ocean Dipole can sometimes reduce the adverse influence of El Niño on the Indian monsoon.
- El Niño is itself a permanent change in Earth’s climate system caused solely by anthropogenic global warming.
Which of the statements given above are correct?
A. 1, 2 and 3 only
B. 1 and 4 only
C. 2 and 3 only
D. 1, 2, 3 and 4
Answer: A
Explanation: El Niño is a recurring climate variability phenomenon. Its influence on the Indian monsoon can be modified by other ocean-atmosphere phenomena, including the Indian Ocean Dipole. It is not itself a permanent anthropogenic climate change phenomenon.
Q11. Which one of the following correctly describes the Walker circulation under normal conditions in the tropical Pacific?
A. A purely polar atmospheric circulation driven by Arctic sea-ice variability.
B. An east-west tropical atmospheric circulation involving rising air over the warmer western Pacific and sinking air over the eastern Pacific.
C. A monsoon circulation restricted entirely to the Indian Ocean.
D. A deep-ocean current flowing from the Pacific towards the Atlantic.
Answer: B
Explanation: Under normal conditions, warmer waters in the western tropical Pacific support strong convection and rising air, while comparatively cooler eastern Pacific waters are associated with subsidence. El Niño alters this ocean-atmosphere circulation.
Q12. A very strong El Niño event may simultaneously create drought risk in some regions and flood risk in others primarily because:
A. El Niño causes uniform rainfall decline across the world.
B. Changes in tropical Pacific ocean-atmosphere conditions alter atmospheric circulation and shift rainfall patterns differently across regions.
C. El Niño directly melts all major glaciers.
D. El Niño affects only ocean temperatures and has no atmospheric consequences.
Answer: B
Explanation: El Niño produces teleconnections—changes in atmospheric circulation that influence rainfall and temperature far beyond the tropical Pacific. Consequently, different regions can experience contrasting impacts, including drought, heavy rainfall and extreme heat.
