The correct option is D) Zemu Glacier – Arunachal Pradesh.
Statement A is correct. Nubra Valley is located in Ladakh (formerly part of Jammu and Kashmir). Significant glaciers like Siachen are in this region.
Statement B is correct. Milam Glacier is located in the Kumaon Himalayas in Uttarakhand.
Statement C is correct. The Bhaga Valley is part of the Lahaul region in Himachal Pradesh, a glaciated area that forms one of the headwaters of the Chandrabhaga (Chenab) river.
Statement D is incorrect. The Zemu Glacier is located in Sikkim, India, on the eastern face of Kangchenjunga. It is the largest glacier in the Eastern Himalayas and is the source of the Teesta River. It is not located in Arunachal Pradesh.
Glaciers in the Himalayas are important sources of water for major river systems in India and surrounding countries. Knowing the location of major glaciers is relevant for understanding regional geography and environmental issues.

The Siachen Glacier is located in the eastern Karakoram range of the Himalayas. Among the given options, it is situated to the north of the Nubra Valley.
The Nubra Valley is a valley formed by the Nubra River, which originates from the Siachen Glacier. Therefore, the glacier is situated upstream and to the north of the valley.
Siachen Glacier is the world’s second largest non-polar glacier. It is located just northeast of the point NJ9842, where the Line of Control between India and Pakistan ends. The area is a disputed territory between India and Pakistan. Geographically, it is west of Aksai Chin and northeast of Leh. Gilgit is located significantly to the northwest of the Siachen region.

The correct answer is A) 1, 2 and 4 only.
This question tests the knowledge of the origin points of major rivers from specific glaciers.
1. Bandarpunch Glacier is the source of the Yamuna River: Correct. The Yamunotri Glacier, which is part of the Bandarpunch massif in Uttarakhand, is the source of the Yamuna River.
2. Bara Shigri Glacier is the source of the Chenab River: Correct. The Bara Shigri Glacier in Himachal Pradesh is the source of the Chandra River, which joins the Bhaga River to form the Chenab River at Tandi.
3. Milam Glacier is the source of the Mandakini River: Incorrect. Milam Glacier in Uttarakhand is the source of the Goriganga River, a tributary of the Kali River. The Mandakini River originates from the Chorabari Glacier near Kedarnath.
4. Siachen Glacier is the source of the Nubra River: Correct. The Siachen Glacier in Ladakh is the source of the Nubra River, a tributary of the Shyok River, which ultimately flows into the Indus River.
5. Zemu Glacier is the source of the Manas River: Incorrect. Zemu Glacier in Sikkim is the source of the Teesta River. The Manas River originates in Bhutan and flows into Assam, India, eventually joining the Brahmaputra River.
Identifying the sources of rivers from glaciers is a common topic in Indian geography. Based on the confirmed sources, pairs 1, 2, and 4 are correctly matched, while 3 and 5 are incorrect.

If you want to observe moraines, eskers and outwash plains, which one of the following Union Territories you may have to visit?

UPSC NDA-1 – 2022

The correct answer is D) Ladakh.
Moraines, eskers, and outwash plains are all glacial landforms. Moraines are accumulations of glacial debris, eskers are long, winding ridges composed of stratified sand and gravel deposited by glacial meltwater streams, and outwash plains are broad, flat areas of gravel, sand, and silt deposited by meltwater streams flowing from a glacier. Ladakh is a high-altitude desert region in the Himalayas with significant past and present glaciation, making it a place where these landforms can be observed.
Andaman and Nicobar Islands, Lakshadweep, and Puducherry are all located in tropical or coastal areas with no significant glacial history or present-day glaciers.

Urdok glacier is located in the Karakoram mountain range, specifically in the Siachen Muztagh area, which is far to the north of the Pir Panjal Range. Sonapani and Bara Shigri are well-known glaciers located in Himachal Pradesh, with Sonapani situated within the Lahaul region which is associated with the Pir Panjal range. Bara Shigri is a large glacier often considered part of the Greater Himalayas or Zanskar range, adjacent to Pir Panjal. Gangri glacier is also located in HP, near the Bara Shigri system. Among the options, Urdok is definitively not part of the Pir Panjal Range.
– The Pir Panjal Range is part of the Lesser Himalayas.
– Urdok glacier is located in the Karakoram range.
– Sonapani and Bara Shigri are glaciers found in Himachal Pradesh, near the Pir Panjal and Greater Himalayan ranges.
The Pir Panjal Range is the largest range of the Lesser Himalayas, extending from the Jhelum River in Jammu and Kashmir to the upper Beas River in Himachal Pradesh. The Karakoram Range is a separate mountain system located to the north of the Himalayas, including peaks like K2 and major glaciers like Siachen.

Let’s evaluate each pair of Himalayan Glaciers and their location:
1. Siachen – Nubra Valley Region: The Siachen Glacier is located in the Eastern Karakoram range. The meltwater from the glacier forms the Nubra River, which flows through the Nubra Valley. Thus, the glacier is directly related to and located within the geographical context of the Nubra Valley. This pair is correctly matched.
2. Chungphar – Kumaon-Garhwal Region: The Chungphar Glacier is located in the Karakoram range, specifically in the Gilgit-Baltistan region. Glaciers in the Kumaon-Garhwal region include Gangotri, Milam, Pindari, etc. This pair is incorrectly matched.
3. Zemu – Central Nepal Region: The Zemu Glacier is located in Sikkim, India, at the base of Mount Kanchenjunga. It is the source of the Teesta River. Glaciers in Central Nepal include Langtang, Khumbu, etc. This pair is incorrectly matched.
4. Gasherbrum – Pir Panjal Range: The Gasherbrum peaks and glaciers are located in the Karakoram range, part of the Baltoro Muztagh region. The Pir Panjal Range is part of the Lesser Himalayas, much further south. This pair is incorrectly matched.
Only pair 1 is correctly matched.
– Siachen Glacier is in the Eastern Karakoram and feeds the Nubra River in the Nubra Valley.
– Chungphar Glacier is in the Karakoram.
– Zemu Glacier is in Sikkim, India.
– Gasherbrum Glacier is in the Karakoram.
– Pir Panjal Range is in the Lesser Himalayas.
Himalayan glaciers are major sources of water for many of the great rivers of South Asia. They are found across various ranges of the Himalayas and Karakoram, including the Great Himalayas, Lesser Himalayas, and Trans-Himalayas (like Karakoram). Their location and health are crucial for regional water security and climate studies.
