Correct Option
The correct option is 1, 2, 3 and 4
Explanation
The Himalayas are divided longitudinally into distinct regions from west to east. These divisions are demarcated by deep river valleys that cut across the mountain ranges. This classification, originally proposed by Sir Sidney Burrard, segments the mountain system based on the major rivers flowing through it.
Statement-wise Analysis
- Statement 1 is Correct: The Punjab Himalayas (also known as the Kashmir and Himachal Himalayas) are situated between the Indus and Satluj rivers. This section covers a stretch of approximately 560 km.
- Statement 2 is Correct: The Kumaon Himalayas lie between the Satluj and Kali rivers. This section extends for about 320 km and includes major peaks like Nanda Devi, Kamet, and Trisul.
- Statement 3 is Correct: The Nepal Himalayas are situated between the Kali and Teesta rivers. This is the longest section (approx. 800 km) and contains some of the highest peaks in the world, including Mount Everest, Kanchenjunga, and Dhaulagiri.
- Statement 4 is Correct: The Assam Himalayas lie between the Teesta and Dihang (Brahmaputra) rivers. This section spans approximately 720 km and covers the easternmost part of the Himalayan range.
Key Takeaway: The longitudinal division of the Himalayas from West to East follows the sequence of rivers: Indus → Satluj → Kali → Teesta → Dihang, corresponding to the Punjab, Kumaon, Nepal, and Assam Himalayas respectively.
