Q. Consider the following pairs: (Himalayas lying between : River Valleys)

1. Indus and Satluj: Punjab Himalaya
2. Satluj and Kali rivers: Kumaon Himalayas
3. Kali and Teesta: Assam Himalayas
4. Teesta and Dihang rivers: Nepal Himalayas

Which of the above is/are matched incorrectly?
Answer: Only 3 and 4
Notes: The Himalayas have been divided on the basis of regions from west to east. These divisions have been demarcated by river valleys. For example, the part of Himalayas lying between Indus and Satluj has been traditionally known as Punjab Himalaya but it is also known regionally as Kashmir and Himachal Himalaya from west to east respectively. The part of the Himalayas lying between Satluj and Kali rivers is known as Kumaon Himalayas. The Kali and Teesta rivers demarcate the Nepal Himalayas and the part lying between Teesta and Dihang rivers is known as Assam Himalayas.
