FAQs on Physiography of india (Part - 2) - Geography, UPSC Video Lecture

1. What is the significance of physiography in the geography of India?
Ans. Physiography plays a crucial role in understanding the geography of India. It helps in studying the landforms, relief features, and the overall physical characteristics of the country. By analyzing the physiography, one can determine the distribution of mountains, plateaus, plains, rivers, and other natural features, which in turn influence climate, vegetation, and human activities.
2. What are the major physiographic divisions of India?
Ans. India is divided into six major physiographic divisions. These include the Himalayan region, the Northern Plains, the Peninsular Plateau, the Indian Desert, the Coastal Plains, and the Islands. Each division has distinct landforms, geological history, and ecological features.
3. How does the physiography of India contribute to its climatic diversity?
Ans. The physiography of India greatly influences its climatic diversity. For example, the presence of the Himalayas acts as a barrier to the cold winds from Central Asia, resulting in the Indian subcontinent having a predominantly tropical monsoon climate. The Northern Plains, being a flat and fertile region, experience hot summers and cold winters. The Western Ghats and the Eastern Ghats modify the climate on the coastal plains, leading to high rainfall. Thus, the varied landforms contribute to the diverse climatic conditions across the country.
4. What are the major rivers associated with the physiography of India?
Ans. The major rivers associated with the physiography of India are the Indus, Ganges, Brahmaputra, Godavari, Krishna, and Mahanadi. These rivers have shaped the landforms and influenced the settlement patterns, agriculture, and economic activities in their respective regions. The Himalayan rivers, originating from the snow-capped mountains, are perennial and a vital source of water for irrigation and hydropower generation.
5. How does the physiography of India impact its biodiversity?
Ans. The physiography of India contributes significantly to its biodiversity. The diverse landforms provide varied habitats for different species of flora and fauna. For example, the Western Ghats are a biodiversity hotspot, hosting numerous endemic plant and animal species. The Himalayas are home to unique fauna such as snow leopards, Himalayan monal, and red pandas. The coastal plains and islands support marine biodiversity with coral reefs and mangrove forests. Thus, the physiography of India plays a crucial role in supporting a rich and diverse ecosystem.
