Tributaries of the Indus River

The correct answer is option 'A', Indus.

The Indus River is one of the longest rivers in Asia, flowing through Pakistan, India, and China. It originates in the Tibetan plateau and traverses through the Himalayas, Karakoram, and the Hindu Kush mountain ranges before finally entering the Arabian Sea.

The Indus River has several tributaries that contribute to its flow and water volume. Four of the significant tributaries of the Indus River are:

1. Zaskar River:
- The Zaskar River is a tributary of the Indus River and is located in the northernmost part of India.
- It originates in the Zaskar Range of the Himalayas and flows through the regions of Ladakh and Zanskar.
- The Zaskar River meets the Indus River near the town of Nimmu in Jammu and Kashmir.

2. Nubra River:
- The Nubra River is another tributary of the Indus River and is also situated in the Ladakh region of India.
- It originates from the Siachen Glacier, which is one of the largest glaciers outside the polar regions.
- The Nubra River flows through the Nubra Valley and joins the Shyok River, a major tributary of the Indus River.

3. Shyok River:
- The Shyok River is a significant tributary of the Indus River and is located in the Ladakh region of India and the Gilgit-Baltistan region of Pakistan.
- It originates from the Rimo Glacier, which is one of the largest glaciers in the Karakoram Range.
- The Shyok River flows through the Shyok Valley and joins the Nubra River before finally merging with the Indus River near Skardu in Pakistan.

4. Hunza River:
- The Hunza River is yet another tributary of the Indus River, located in the Gilgit-Baltistan region of Pakistan.
- It originates from the Khunjerab Pass, which is the highest paved international border crossing in the world.
- The Hunza River flows through the Hunza Valley and joins the Gilgit River before eventually merging with the Indus River.

These four tributaries, the Zaskar, Nubra, Shyok, and Hunza, play a vital role in contributing water to the Indus River system. They not only provide water for irrigation and drinking purposes but also support the diverse ecosystems and wildlife along their courses. The Indus River and its tributaries are of immense importance to the people and environment of the region, making it a lifeline for millions of people who depend on its resources.
