In NEWS: How can State PSCs be reformed?

Public Service Commissions (PSCs) in India:

• The first Public Service Commission in India was established in 1926 under the provisions of the Government of India Act, 1919, following the Montagu–Chelmsford Reforms. Hence statement 1 is incorrect.
• The Montagu–Chelmsford Report (1918) recommended the creation of a permanent, independent Public Service Commission to ensure merit-based recruitment free from political influence. Hence statement 2 is correct.
• The Government of India Act, 1935 provided for the establishment of Provincial (State) Public Service Commissions.
• Articles 315 to 323 of the Constitution provide for the establishment, composition, tenure, removal, and powers of the UPSC and State PSCs.
• The Constitution does not prescribe minimum age, qualifications, or prior experience for appointment as members of the UPSC or State PSCs. Hence statement 3 is incorrect.
• The 41st Constitutional Amendment Act, 1976 increased the upper age limit of State PSC members from 60 to 62 years.
• The UPSC functions in a comparatively politically sterile environment, while State PSCs operate in a politically osmotic environment with visible influence on appointments.
• The Ministry of Personnel, Public Grievances and Pensions, created in 1985, ensures systematic manpower planning and timely vacancy notifications for UPSC examinations.
• Most States lack a dedicated personnel ministry, leading to irregular vacancy notifications and delayed recruitment cycles.
• UPSC periodically revises its syllabus through expert committees, whereas most State PSCs rarely update their syllabi.
• UPSC uses inter-se moderation to reduce subjectivity in evaluation; State PSCs often struggle with this process.
• State PSCs face increased litigation due to issues in vertical, horizontal, and zonal reservation calculations and translation errors between English and regional languages.
• Reforms suggested include setting a minimum age of 55 and maximum age of 65 for PSC members along with clearly defined qualifications.
• It is recommended that syllabus revision proposals be placed in the public domain and finalised after public consultation.
• A senior officer with experience in school or intermediate education administration should serve as the Secretary of State PSCs to improve exam management.

5. Consider the following statements regarding mosses (Bryophytes):

1. Some mosses can survive complete desiccation and revive upon rehydration.

2. Some mosses can tolerate high levels of radiation, including those found in outer space.

3. Some mosses can act as bioindicators of air pollution.

4. Some mosses can perform nitrogen fixation.

How many of the above statements are correct?

(a) Only one

(b) Only two

(c) Only three

(d) All four

Answer: (c) Only three

Explanation:

In NEWS: Moss spores survive months in space: Why is this significant?

Characteristics of Moss Spores:

Desiccation Tolerance:

• Certain mosses such as Tortula ruralis and Syntrichia caninervis can survive up to 95% water loss.
• These mosses revive completely when water becomes available again.
• Desiccation tolerance in mosses is enabled by protective proteins, sugar molecules like trehalose, and flexible cell walls.
• This trait evolved because mosses are among the earliest land plants, exposed to harsh terrestrial conditions.

Radiation and Space Survival

• Moss spores of Physcomitrium patens survived 283 days outside the International Space Station (ISS).
• Over 80% of the exposed moss spores remained viable and successfully germinated after returning to Earth.
• Moss spores tolerate cosmic radiation, UV exposure, extreme temperatures, and vacuum.
• Multi-layered spore walls act as natural “passive shields’’ against radiation damage.
• Space-modelling studies estimate that moss spores could survive in outer space for up to 15 years.

Bioindicator Role

• Mosses absorb nutrients and contaminants directly from the atmosphere, not through roots.
• This enables them to accumulate heavy metals, SO₂, NOx, and organic pollutants from the air.
• Mosses are widely used in moss monitoring programs for air-quality assessment in Europe and Asia.
• Species such as Hypnum cupressiforme and Pleurozium schreberi are standard bioindicator mosses.

Nitrogen Fixation Myth

• Mosses do not perform nitrogen fixation themselves. Hence 4 is incorrect.
• Nitrogen fixation occurs via cyanobacteria living on the surface of mosses, especially on Sphagnum moss.
• Ecosystems benefit from nitrogen fixed by cyanobacteria, but the moss is not the nitrogen-fixing organism.

Significance of Moss

• Mosses demonstrate ancient plant survival strategies, helping scientists understand early plant evolution on land.
• Their desiccation tolerance serves as a model for improving drought resistance in modern crops.
• Their ability to survive cosmic radiation and vacuum provides insights into the possibility of life enduring harsh extraterrestrial environments.
• Moss spores surviving on the ISS show potential for bio-regenerative life-support systems in future lunar and Martian habitats.
• Mosses contribute to carbon sequestration, especially in peatlands dominated by Sphagnum species.
• Moss-dominated peatlands store nearly 30% of global soil carbon, making them crucial in climate regulation.
• Mosses act as low-cost bioindicators for monitoring air quality and heavy-metal pollution.
• Their sensitivity to atmospheric contaminants helps governments design pollution-control policies.
• In ecosystems, mosses help in soil formation, moisture retention, and preventing erosion.
• Moss–cyanobacteria associations enhance nitrogen input into nutrient-poor ecosystems, supporting biodiversity.
• Understanding moss stress tolerance aids biotechnology research in stress-resistant biomaterials.
• Their space survival provides evidence relevant to astrobiology, particularly studies on panspermia (life dispersal).

7. Which one of the following statements best describes ‘Fujiwhara interaction’, recently seen in the news?

(a) The interaction between warm and cold ocean currents leading to rapid cyclogenesis.

(b) The phenomenon in which two nearby cyclonic systems rotate around a common centre and influence each other’s movement.

(c) The sudden intensification of a tropical cyclone due to a burst of deep convection near the eyewall.

(d) The reversal of wind patterns in the equatorial Pacific associated with El Niño events.

Answer: (b) The phenomenon in which two nearby cyclonic systems rotate around a common centre and influence each other’s movement.

Explanation:

In NEWS: Multiple cyclonic storms with rare Fujiwhara interaction likely in Bay of Bengal

• Two cyclonic systems are forecast to form in the Bay of Bengal within a short time of each other, raising the possibility of a Fujiwhara-type interaction.
• This interaction could increase uncertainty around their future track and intensity, making forecasting more difficult.
• The India Meteorological Department (IMD) is closely monitoring both systems:
• One system is expected to develop from a low-pressure area over the Straits of Malacca and intensify into a cyclone in the south Bay of Bengal by around November 27.
• It is linked to an upper-air cyclonic circulation over the Comorin area, which may lead to another depression forming over the southwest Bay of Bengal or near Sri Lanka.

Fujiwhara Interaction:

• The Fujiwhara interaction is a phenomenon in which two nearby cyclonic systems come close enough that their circulations begin to influence each other. When this happens, the storms may:
  • Rotate around a common centre,
  • Alter each other’s tracks,
  • Move closer and merge, or
  • Weaken or intensify depending on their relative strengths.
• This interaction usually occurs when two cyclones are within about 1,000 km of each other. It makes forecasting more difficult because the storms’ movements become more unpredictable.

Hence option (b) is correct.

8. The ‘Hayli Gubbi’ volcano, recently seen in the news is a

(a) Shield volcano

(b) Composite volcano

(c) Caldera

(d) Cinder cone volcano

Answer: (a) Shield volcano

Explanation:

In NEWS: India braces for disruption of air travel after Ethiopia’s Hayli Gubbi volcano erupts

Hayli Gubbi Volcano:

• It is located in the Afar Region of northeastern Ethiopia, part of the tectonically active Erta Ale Range.
• It is a shield volcano, characterized by gentle slopes formed by low-viscosity lava flows. Hence option (a) is correct.
• The summit of the volcano is approximately 493 meters above sea level.
• Before 2025, the volcano had been dormant for roughly 10,000–12,000 years, with no recorded eruptions in the Holocene.
• The volcano erupted on 23 November 2025, marking its first activity in millennia.
• The eruption was explosive, producing an ash plume that reached 10–15 km into the atmosphere.
• A significant sulfur-dioxide (SO₂) plume was also emitted during the eruption.
• High-altitude winds carried the volcanic ash across the Red Sea toward Yemen, Oman, and as far as India.
• The eruption is considered rare and significant because of the long dormancy and potential hazards for aviation and the environment.

Causes of Volcanic Eruptions

• Tectonic Plate Movements
  • Divergent boundaries: Plates move apart → magma rises (e.g., Mid-Atlantic Ridge).
  • Convergent boundaries: Subduction zones cause melting → volcanic activity (e.g., Pacific Ring of Fire).
• Hotspots / Mantle Plumes
  • Magma rises through the crust away from plate boundaries (e.g., Hawaii, Iceland).
• Pressure in Magma Chambers
  • Accumulation of magma and gas increases pressure → eruption occurs.
• Weak Zones in the Crust
  • Fissures or fractures allow magma to escape.

Consequences / Impacts of Volcanic Eruptions

A. Environmental Impacts

• Destruction of forests, farmland, and natural habitats
• Air pollution due to ash and gases (SO₂, CO₂)
• Climate effects: short-term cooling from ash and SO₂

B. Human / Social Impacts

• Loss of life and injuries from lava flows, pyroclastic flows, and ashfall
• Displacement of populations and destruction of homes

C. Economic Impacts

• Damage to infrastructure (roads, bridges, airports)
• Disruption of trade, tourism, and agriculture

D. Health Impacts

• Respiratory problems and diseases from inhaling ash and toxic gases

E. Positive / Beneficial Impacts

• Formation of fertile soils for agriculture
• Creation of new land and volcanic islands
• Potential for geothermal energy

9. Consider the following statements:

Statement-I: Nearly 70% of corals faced destruction at the UNESCO-listed Ningaloo Reef.

Statement-II: Recently, an unprecedented marine heat wave occurred in Western Australia.

Which one of the following is correct in respect of the above statements?

(a) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I

(b) Both Statement-I and Statement-II are correct, but Statement-II does not explain Statement-I

(c) Statement-I is correct, but Statement-II is incorrect

(d) Statement-I is incorrect, but Statement-II is correct

Answer: (a) Both Statement-I and Statement-II are correct and Statement-II explains Statement-I

Explanation:

In NEWS: ‘Unprecedented’ heatwave kills nearly two-thirds of corals at UNESCO-listed Ningaloo Reef

Ningaloo Reef:

• An unprecedented marine heatwave has killed nearly 70% of corals at the UNESCO-listed Ningaloo Reef in Western Australia. Hence both Statement-I and Statement-II are correct and Statement-II explains Statement-I
• The reef’s northern lagoon, covering eight survey sites, now shows more than 60% coral mortality.
• In March, researchers counted over 1,600 individual corals; by October, only about 600 remained alive.
• The heatwave was described as the longest, largest, and most intense “underwater” heatwave ever recorded in Australia.
• The reef was already under stress before this event: in 2022, low oxygen levels caused a sharp drop in live coral cover in some areas.
• On a global scale, bleaching-level heat stress has affected a very large portion of reefs: according to NOAA data cited, about 84.4% of the world’s coral reef area has been exposed to such stress.

Threats to corals:

• Rising sea temperatures cause coral bleaching and mass mortality.
• Ocean acidification reduces coral growth and weakens reef structures.
• Marine heatwaves lead to widespread coral stress and die-offs.
• Cyclones and storms physically damage and break coral reefs.
• Sedimentation from land runoff smothers corals and blocks sunlight.
• Nutrient pollution promotes algal blooms that outcompete corals.
• Chemical pollution (oil, toxins, sunscreen) poisons coral tissues.
• Plastic pollution injures corals and increases disease risk.
• Coastal development destroys reef habitats and increases turbidity.
• Overfishing disrupts reef food webs and promotes algal overgrowth.
• Destructive fishing (blast, cyanide) directly kills corals.
• Invasive species like crown-of-thorns starfish consume corals rapidly.
• Coral diseases spread faster under warm and polluted conditions.
• Ship groundings and anchors physically crush and break reefs.
• Tourism pressure causes physical damage and chemical contamination.
• Increased UV radiation stresses and bleaches corals.
• Climate change intensifies multiple stressors, reducing coral resilience.
