Q2. Explain the role of plate tectonics in shaping India’s physiographic divisions. Discuss its implications for natural hazards and resource distribution. (10 M)
Difficulty Level: Medium
Reference: InsightsIAS
Why the question Geological events such as the Land subsidence and frequent Himalayan earthquakes have reignited focus on tectonic processes shaping India’s terrain and vulnerability. Key Demand of the question The question requires explanation of how plate tectonics influenced India’s landform evolution and how these features contribute to natural hazards and determine resource distribution across regions. Structure of the Answer: Introduction Briefly state how India’s physiography is a product of ancient and ongoing tectonic activity, making it geologically diverse and active. Body Role of plate tectonics in shaping landforms: Mention Himalayan uplift, Peninsular faults, volcanic regions, and sedimentary basins. Implications for natural hazards: Include seismicity, landslides, tsunamis, and volcanism. Implications for resource distribution: Cover minerals in shields, hydrocarbons in basins, fertile soils, and aquifers. Conclusion Highlight the dual nature of tectonics as both a threat and a resource-enabler, stressing on sustainable geo-management.
