Physical Geography of India
India's physiography is diverse — the Himalayas, Indo-Gangetic plains, Peninsular plateau, coastal plains, and islands. Understanding landforms is crucial for both Prelims and Mains GS Paper 1.
Major Physiographic Divisions
- The Himalayas: Three parallel ranges — Greater (Himadri), Lesser (Himachal), Outer (Shivalik). Formed by collision of Indo-Australian & Eurasian plates. Young fold mountains.
- Northern Plains: Formed by alluvial deposits of Indus, Ganga, Brahmaputra. Bhangar (old alluvium), Khadar (new alluvium), Terai (marshy, dense forest), Bhabar (pebble bed near Shivalik).
- Peninsular Plateau: Oldest landmass. Made of igneous & metamorphic rocks. Western Ghats, Eastern Ghats, Deccan Plateau, Chota Nagpur Plateau (jharkhand — mineral rich).
- Coastal Plains: Western Coast (narrow, Konkan + Malabar). Eastern Coast (wider, Coromandel + Northern Circar). Lagoons — Chilika, Pulicat, Vembanad.
- SW Monsoon (June–Sep): Arabian Sea branch (Kerala → west coast, Western Ghats get heavy rain — windward side). Bay of Bengal branch (NE India, Bangladesh, then westward).
- NE Monsoon (Oct–Dec): Retreating. Tamil Nadu coast gets rain (Bay of Bengal picks up moisture).
- Mawsynram, Meghalaya — Highest rainfall in world (~11,872 mm/year). Cherrapunji (Sohra) — 2nd highest.
- Rain Shadow Area: Leeward side of Western Ghats (Deccan Plateau) — low rainfall. Pune gets less than Mumbai.
