Read this question in English

Siachen Glacier is situated to the

(a) East of Aksai Chin · (b) East of Leh · (c) North of Gilgit · (d) North of Nubra Valley

उत्तर और व्याख्या · explanation in English

Answer: (d) नुब्रा घाटी के उत्तर में

Siachen Glacier lies in the eastern Karakoram range, up the Nubra Valley of Ladakh, so it is north of the Nubra Valley. It is not east of Leh, east of Aksai Chin or north of Gilgit.

  • ✓ (d) The Nubra Valley runs up towards the Siachen Glacier, which sits at its head in the eastern Karakoram; the glacier is therefore north of the valley.
  • ✗ (b) Siachen is north of Leh, across the Ladakh range and the Nubra and Shyok valleys, not to its east.
  • ✗ (c) Gilgit lies to the west of the Karakoram range, so Siachen is south-east of Gilgit, not north of it.
  • ✗ (a) Aksai Chin is on the plateau to the east of the Karakoram, so Siachen lies west of it.

Remember · Siachen Glacier: eastern Karakoram, at the head of the Nubra Valley, Ladakh; the Nubra River begins from its snout.
