FAQs on Physiographic Divisions of India

Question 1

1. What are the main physiographic divisions of India and how are they different from each other?

Accepted Answer

Ans. India's physiographic divisions include the Himalayan Mountains, Indo-Gangetic Plains, Deccan Plateau, Coastal Plains, and Islands. Each division has distinct geographical features-the Himalayas are young fold mountains with high peaks, the Indo-Gangetic Plains feature alluvial fertile soil, the Deccan Plateau is an elevated tableland, and coastal plains border the oceans. These regions differ in terrain, climate, vegetation, and human settlement patterns.

Question 2

2. How does the structure of the Indo-Gangetic Plain differ from the Deccan Plateau in terms of formation and characteristics?

Accepted Answer

Ans. The Indo-Gangetic Plain formed from alluvial deposits by rivers and features flat, low-lying terrain ideal for agriculture. The Deccan Plateau, conversely, is an ancient block mountain with elevated tableland topography, formed by volcanic activity and erosion. Plains have rich soil and higher rainfall; plateaus experience varied drainage patterns and are composed of lava flows and metamorphic rocks.

Question 3

3. Why are the Himalayan Mountains considered young fold mountains, and what makes them different from the Deccan Plateau?

Accepted Answer

Ans. Young fold mountains like the Himalayas formed recently through tectonic plate collision, creating steep slopes, high altitudes, and ongoing geological activity including earthquakes. The Deccan Plateau, an ancient block mountain, formed billions of years ago and is relatively stable with moderate elevation. Himalayan ranges continue rising; plateaus remain geologically dormant with gradual erosion.

Question 4

4. What role do physiographic divisions play in determining India's climate, vegetation, and human settlement patterns?

Accepted Answer

Ans. Physiographic divisions directly shape India's regional climates-Himalayas cause precipitation variation, plains experience monsoons, and plateaus have moderate conditions. Vegetation adapts accordingly: forests in mountains, grasslands on plains, and scrub on plateaus. Human settlements concentrate in fertile Indo-Gangetic Plains and coastal regions due to advantageous terrain and climate for agriculture and commerce.

Question 5

5. How can I remember the key features and locations of all major physiographic regions for UPSC preparation?

Accepted Answer

Ans. Students preparing for UPSC can use EduRev's mind maps, flashcards, and visual worksheets to systematize physiographic divisions by location, elevation, and characteristics. Group information by region: mountains (Himalayas, Western/Eastern Ghats), plains (Indo-Gangetic), and plateaus (Deccan). Create comparison tables highlighting terrain types, drainage patterns, and climate zones for quick revision during exam preparation.
