🟦 Geography Optional – MAINS
Paper–II : Indian Geography
Page – 16 | Physical Setting of India
UPSC / UPPSC | Shaktimatha 369 Learning
Q16. Examine the geological structure and major physiographic divisions of India. Discuss their influence on drainage, climate and human activities.
Directive: Examine + Discuss (Analytical & Applied)
Introduction
India’s physical setting is the result of long geological evolution, marked by plate movements, folding, faulting and volcanic activity. The diversity of relief forms has significantly influenced natural processes and human settlement patterns.
Main Body
1. Geological Structure of India
- Peninsular Shield: One of the oldest landmasses, stable block
- Himalayan Orogenic Belt: Young fold mountains formed by plate collision
- Indo-Gangetic Plain: Alluvial deposits of Himalayan rivers
- Coastal Plains & Islands: Result of marine and tectonic processes
2. Major Physiographic Divisions
- Himalayas
- Northern Plains
- Peninsular Plateau
- Indian Desert
- Coastal Plains
- Islands
3. Influence on Drainage System
- Himalayas give rise to perennial rivers
- Peninsular rivers are seasonal and structurally controlled
- Drainage patterns reflect geological structure
4. Influence on Climate
- Himalayas act as climatic barrier
- Relief affects monsoon distribution
- Altitude influences temperature variation
5. Influence on Human Activities
- Fertile plains support dense population
- Plateau rich in minerals and industries
- Mountains influence agriculture, tourism and defence
Conclusion
India’s physical diversity forms the foundation of its ecological richness and economic activities. Understanding relief and structure is essential for sustainable development and disaster preparedness.
Maps/Diagrams to draw in exam:
• Physiographic divisions of India
• Major geological structures
• Drainage systems of India
Examiner’s View:
✔ Integrated physical + human linkage scores high
✔ Map is compulsory for 15/20-mark questions
✔ Avoid listing divisions without analysis
