Indian Physical Geography› Himalayas, Peninsular Block, Hills, Peaks and Glaciers

Consider the following pairs : Peak Mountains

  1. 1. Namcha Barwa : Garhwal Himalaya
  2. 2. Nanda Devi : Kumaon Himalaya
  3. 3. Nokrek : Sikkim Himalaya

Which of the pairs given above is/are correctly matched ?

Answer b.

Explanation Answer · b

Option (b): only pair 2 is correct. Nanda Devi is the highest peak of the Kumaon Himalaya; Namcha Barwa is the eastern end of the Himalaya in Tibet, and Nokrek is in the Garo Hills of Meghalaya, not the Himalaya at all. In the classical regional division (Sir Sidney Burrard), the Kumaon Himalaya stretches between the Sutlej and the Kali rivers and its highest peak is Nanda Devi (7,816 m, Chamoli district, Uttarakhand), the highest summit lying entirely within India; NCERT Class 11 groups this as the Himachal and Uttarakhand Himalaya. Namcha Barwa (7,782 m) is the peak around which the Brahmaputra (Yarlung Tsangpo) makes its great bend in Tibet and marks the eastern extremity of the Himalaya, far from Garhwal in western Uttarakhand. Nokrek (1,412 m) is the highest point of the Garo Hills on the Meghalaya plateau, a block of the Peninsular shield, so it cannot belong to the Sikkim Himalaya, whose highest peak is Kangchenjunga.
