Physical Geography of India
Overview
Physical Geography of India is a foundational topic for UPTET Paper II Social Studies, appearing consistently across examinations. This topic tests your understanding of India's natural landscape — its mountains, plateaus, plains, rivers, climate patterns, soil types and vegetation zones. Questions typically ask you to identify locations, match features with regions, or explain relationships between climate and vegetation.
For UPTET, focus on factual accuracy: names, locations, characteristics and simple cause-effect relationships. The examiner expects you to know where the Western Ghats are, which rivers are peninsular versus Himalayan, what type of soil suits cotton cultivation, and how monsoons work. Mastery here also helps with Environmental Studies and general awareness sections.
Since the exam covers UP specifically, pay attention to features relevant to Uttar Pradesh — the Gangetic Plain, the Ganga-Yamuna river system, alluvial soils, and the subtropical climate of the state.

Key Concepts
- **India's location**: Extends from 8°4'N to 37°6'N latitude and 68°7'E to 97°25'E longitude; Tropic of Cancer (23°30'N) passes through eight states including Madhya Pradesh, Gujarat and West Bengal.
- **Six major physiographic divisions**: The Himalayas, Northern Plains, Peninsular Plateau, Coastal Plains, Islands, and the Thar Desert — each with distinct landforms and resources.
- **Himalayas are young fold mountains**: Formed by collision of Indian and Eurasian plates; still rising; prone to earthquakes; three parallel ranges — Himadri (Greater), Himachal (Lesser), Shiwaliks (Outer).
- **Northern Plains are alluvial**: Formed by depositional work of Ganga, Brahmaputra and Indus river systems; divided into Bhabar, Terai, Bhangar (old alluvium) and Khadar (new alluvium).
- **Peninsular Plateau is ancient and stable**: Composed of igneous and metamorphic rocks; includes Deccan Plateau, Central Highlands and Eastern Highlands (Western and Eastern Ghats).
- **Monsoon mechanism**: Seasonal reversal of winds; Southwest monsoon (June–September) brings 75% of annual rainfall; Northeast monsoon affects Tamil Nadu in winter.
- **Soil distribution linked to parent rock and climate**: Alluvial in plains, black (regur) in Deccan, red and laterite in peninsular regions, arid in Rajasthan.
- **Natural vegetation follows rainfall gradient**: Tropical evergreen in high-rainfall areas, deciduous in moderate, thorn forests in arid, alpine in Himalayas.
