UPSC Prelims Quiz: October 27, 2025

Q1. Which one of the following statements best explains the ecological linkage between ‘23for23’ initiative and the trans-Himalayan fauna?
(a)

The initiative integrates protection of apex predators with habitat restoration for prey and associated species.

(b)

It focuses exclusively on the genetic diversity of snow leopards across Indian zoos.

(c)

It seeks to relocate livestock from alpine regions to create inviolate spaces.

(d)

It is a time-bound project aimed at doubling snow-leopard population by 2023.

Explanation

The ‘23for23’ campaign promotes awareness and community participation for conserving the snow-leopard landscape — protecting both predator and prey species (e.g., Urial, Argali, Marmot). It is not a captive-breeding or relocation programme.

Answer: (a)
Q2. With reference to the recent nationwide assessment of the Snow Leopard (Panthera uncia) in India, consider the following statements:

1. The Union Territory of Ladakh accounts for over half of India’s total estimated snow-leopard population.

2. Uttarakhand recorded the second-highest population after Ladakh in the 2025 assessment.

Which of the statements given above is/are correct?

(a)

1 only

(b)

2 only

(c)

Both 1 and 2

(d)

Neither 1 nor 2

Explanation

Statement 1 — Correct: Ladakh hosts about 477 of the 718 snow leopards recorded in India, i.e., over 65% of the total population — the highest regional concentration.

Statement 2 — Incorrect: Uttarakhand’s estimated count (≈71) was lower than Himachal Pradesh (≈51) and also less than the combined total for Arunachal Pradesh + Sikkim (≈61). Thus, it did not rank second after Ladakh.

Answer: (a)
Q3. With reference to the funding structure of the United Nations (UN), consider the following statements:

Statement 2 – Correct: India’s share in the 2024–25 biennium is about 0.21%, confirming it contributes less than 1% of the total UN budget.

Statement 3 – Correct: The United States (≈ 22%), China (≈ 15%), and Japan (≈ 8%) remain the top three contributors.

Statement 4 – Incorrect: The United Kingdom contributes slightly more than France; France is not ahead of the UK in assessed contributions.

(a)

Only one

(b)

Only two

(c)

All three

(d)

Statement 2 – Correct: Warmer sea-surface temperatures intensify cyclones, leading to stronger storm surges.

Statement 3 – Correct: The region’s deltaic and estuarine coasts increase inundation risk due to low elevation and shallow gradients.

Answer: (c)
Q9. With reference to the naming of tropical cyclones over the North Indian Ocean, consider the following statements:

(a)

1 and 2 only

(b)

1 and 3 only

(c)

2 and 3 only

(d)

All three

Explanation

Statement 1 – Correct: The WMO/ESCAP Panel on Tropical Cyclones agreed to the naming system in 2000, but the actual practice of naming cyclones in the North Indian Ocean officially started in September 2004 with Cyclone Onil.

Statement 2 – Correct: In April 2020, a new list of 169 names was adopted by the WMO/ESCAP panel members. The list included 13 names from each of the 13 member countries in the region, including India, Bangladesh, Iran, Maldives, Myanmar, Oman, Pakistan, Qatar, Saudi Arabia, Sri Lanka, Thailand, United Arab Emirates, and Yemen.

Statement 3 – Incorrect: Unlike some other ocean basins where names are recycled on a rotational basis, the names of tropical cyclones over the North Indian Ocean are not repeated. Once a name is used, it is retired and cannot be used again.

(c)

2 and 3 only

(d)

All three

Explanation

Statement 1 – Correct: These eight nations were the original members of the WMO/ESCAP Panel on Tropical Cyclones.

Statement 2 – Correct: In 2018, five West Asian countries were added, expanding membership to 13 nations.

Statement 3 – Incorrect: Cyclones crossing basins retain their original names and are not renamed upon entering the Bay of Bengal.

Answer: (a)
Cyclones in the Indian Ocean Region

A cyclone is a large system of air rotating around a low-pressure centre. It brings strong winds, heavy rainfall, and turbulent weather.

  • In the Northern Hemisphere, winds rotate anticlockwise.
  • In the Southern Hemisphere, they rotate clockwise.

Cyclones occur over warm oceans and can cause massive destruction when they make landfall.

Types of Cyclones
  • Tropical Cyclones: Form over warm ocean waters near the equator. They have a warm core and derive energy from the latent heat released when moist air rises and condenses into clouds.
  • Extratropical Cyclones: Develop outside the tropics. They have a cold core and gain strength when cold and warm air masses interact in mid-latitude regions.
Why the Bay of Bengal Faces More Cyclones
  • Funnel-like Shape: The Bay’s unique shape concentrates atmospheric disturbances and amplifies storm surges.
  • Complex Coastline: Estuaries, deltas, and pocket bays along the coast influence how water and winds move during storms.
  • Warm Sea Surface: The Bay of Bengal is usually warmer than the Arabian Sea, providing more energy for cyclone formation.
  • Climate Change Effect: Rising sea temperatures have increased cyclone intensity, and the western coast of India is now also witnessing stronger storms.
Storm Surges and Coastal Impact

Storm surges — sudden rises in sea level due to cyclone winds — cause most of the destruction. Their impact depends on:

  • The shape of the coastline,
  • The presence of barriers such as mangroves, dunes, or embankments, and
  • The depth and slope of the sea near the shore.
Naming of Cyclones
  • In 2000, eight countries — Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka, and Thailand — under the WMO/ESCAP Panel on Tropical Cyclones decided to name cyclones in rotation.
  • The system began officially in 2004.
  • In 2018, five new members joined: Iran, Qatar, Saudi Arabia, the UAE, and Yemen.
  • Each of the 13 countries submits 13 names, making a total list of 169 cyclone names (as per the IMD’s 2020 release).
Key Points
  • Cyclones rotate around low-pressure centres and draw energy from warm ocean waters.
  • The Bay of Bengal is India’s most cyclone-prone region.
  • Extratropical cyclones occur in higher latitudes with cold air cores.
  • The WMO/ESCAP naming system helps improve communication and disaster preparedness.
