Match the climate and atmospheric processes in List-I with their corresponding physical mechanisms or environmental impacts in List-II:

Click a left item, then click its matching right item

Show answer & explanation

Answer

Steric Sea Level Rise corresponds to the thermal expansion of seawater driven by heat absorption; Ice-Albedo Positive Feedback corresponds to accelerated warming as reflective ice turns to dark ocean water; Stratospheric Cooling corresponds to thermal contraction in upper layers due to longwave trapping in the troposphere; and Heterogeneous Ozone Catalysis corresponds to rapid conversion of chlorine reservoir species on polar stratospheric cloud particles.

Each item in List-I correctly matches its defining physical or chemical mechanism in List-II based on established atmospheric science: Steric Sea Level Rise is caused by thermal ocean expansion; Ice-Albedo Feedback amplifies warming via reflectivity loss; Stratospheric Cooling is a signature of tropospheric greenhouse trapping; and Heterogeneous Ozone Catalysis occurs on polar stratospheric cloud particle surfaces.

Step-by-Step Solution

Analyze Steric Sea Level Rise

Steric rise is driven by thermal expansion (density reduction of water as temperature rises), matching the thermal expansion description.

Sea level rise has two main components: eustatic (ice melt) and steric (thermal expansion).

Analyze Ice-Albedo Positive Feedback

Decreasing ice cover lowers surface albedo, absorbing more solar radiation and magnifying temperature increases.

Albedo measures surface reflectivity; replacing high-albedo ice (

0.8-0.9

) with low-albedo ocean (

0.06

) creates a self-reinforcing warming loop.

Analyze Stratospheric Cooling

Increased greenhouse gases trap heat in the troposphere, reducing infrared flux reaching the stratosphere and causing it to cool.

Stratospheric cooling is a primary fingerprint distinguishing greenhouse-driven warming from solar irradiance changes.

Analyze Heterogeneous Ozone Catalysis

Polar Stratospheric Clouds (PSCs) provide solid surfaces for reactions converting inactive chlorine reservoirs into photolytically active forms.

Gas-phase reactions alone are too slow to account for Antarctic spring ozone hole formation; surface reactions on PSC particles are essential.

Key Concept

Show answer & explanation

Answer

The correct matching pairs Western Ghats Hotspot with the western peninsular mountain chain (Lion-tailed Macaque and Nilgiri Tahr); Indo-Burma Hotspot with Northeast India south of the Brahmaputra River (Sangai deer); Sundaland Hotspot with the Nicobar group of islands (Nicobar Tree Shrew); and Himalayan Hotspot with the high-altitude montane zone of North and Northeast India (Namdapha Flying Squirrel).

The global biodiversity hotspots overlapping India possess precise biogeographical limits and signature endemic species: Western Ghats (peninsular mountain range with Lion-tailed Macaque), Indo-Burma (Northeast India south of Brahmaputra with Sangai deer), Sundaland (Nicobar Islands with Nicobar Tree Shrew), and Himalayas (montane North/Northeast India with Namdapha Flying Squirrel).

Step-by-Step Solution

Analyze the spatial extent and endemic species of peninsular Western India.

The Western Ghats Hotspot corresponds to the western peninsular mountain chain hosting the Lion-tailed Macaque.

The Western Ghats form a continuous hill chain along peninsular India with exceptionally high endemism.

Delineate the Indian boundary of the Indo-Burma Hotspot.

Indo-Burma pairs with Northeast India south of the Brahmaputra River, including Manipur where the Sangai is endemic.

The Brahmaputra River serves as a major biogeographical dividing line between the Himalayan and Indo-Burma hotspots.

Identify the specific Indian island territory included within Sundaland.

Sundaland pairs exclusively with the Nicobar group of islands, home to the endemic Nicobar Tree Shrew.

While the Andaman Islands belong to Indo-Burma, the Nicobar Islands form the northwestern boundary of the Indo-Malayan Sundaland hotspot.

Map the Himalayan Hotspot to its spatial boundary and endemic fauna.

Himalayan Hotspot pairs with the northern and northeastern high-altitude montane zone hosting the Namdapha Flying Squirrel.

The Himalayan mountain chain covers the high-elevation ecosystems of northern India and areas north of the Brahmaputra.
