Which one of the following Himalayan rivers does NOT originate from across the Himalayas?

  1. A.Indus
  2. B.Satluj
  3. C.Ganga
  4. D.Brahmaputra

Correct answer

C. Ganga

Explanation

The correct answer is C, Ganga. The Ganga rises on the Indian side of the Great Himalaya, at the Gangotri glacier in Uttarakhand, while the Indus, the Satluj and the Brahmaputra all rise beyond the Himalaya in Tibet.

The Bhagirathi, the headstream of the Ganga, emerges from the snout of the Gangotri glacier at Gaumukh and becomes the Ganga after meeting the Alaknanda at Devprayag. The Indus, the Satluj and the Brahmaputra begin on the Tibetan plateau near Lake Mansarovar and Mount Kailash. They are older than the Himalaya itself and kept cutting down as the mountains rose, which is why they are called antecedent rivers and why they flow through very deep gorges.

A is wrong: the Indus rises in Tibet near Lake Mansarovar and enters India in Ladakh. B is wrong: the Satluj rises at Rakas Tal near Mansarovar and enters India at Shipki La. D is wrong: the Brahmaputra rises as the Tsangpo near Mansarovar and enters India in Arunachal Pradesh.

Exam tip: Indus, Satluj and Brahmaputra are trans-Himalayan antecedent rivers from near Mansarovar; the Ganga starts at Gangotri-Gaumukh in India.
