Consider the following pairs: Glacier : River 1. Bandarpunch : Yamuna 2. Bara Shigri : Chenab 3. Milam : Mandakini 4. Siachen : Nubra 5. Zemu : Manas Which of the pairs given above are correctly matched?

  1. A.1, 2 and 4
  2. B.1, 3 and 4
  3. C.2 and 5
  4. D.3 and 5

Correct answer

A. 1, 2 and 4

Explanation

The correct answer is A, 1, 2 and 4. Bandarpunch feeds the Yamuna, Bara Shigri the Chenab and Siachen the Nubra; pairs 3 and 5 are wrong.

The Yamunotri glacier, the source of the Yamuna, lies on the western slopes of the Bandarpunch massif in Uttarakhand. Bara Shigri, one of the largest glaciers of Himachal Pradesh, lies in Lahaul-Spiti and drains into the Chandra river, which joins the Bhaga to form the Chandrabhaga or Chenab. The Siachen glacier in the eastern Karakoram is the source of the Nubra river, a tributary of the Shyok.

Pair 3 is wrong: the Milam glacier in Pithoragarh district is the source of the Gori Ganga; the Mandakini rises from the Chorabari glacier near Kedarnath. Pair 5 is wrong: the Zemu glacier on Kanchenjunga in Sikkim feeds the Teesta, while the Manas flows from Bhutan into Assam.

So B is wrong because it includes pair 3 and leaves out 2, C is wrong because pair 5 is false, and D is wrong because both its pairs are false.

Exam tip: Gangotri–Bhagirathi, Yamunotri (Bandarpunch)–Yamuna, Milam–Gori Ganga, Zemu–Teesta, Siachen–Nubra.
