Explanations:The concept of a watershed is fundamental in geography and refers to the area of land where all the water that falls on it and drains off it goes into the same place. In the context of the question, the watershed between India and Myanmar is formed by the Naga hills, which are a significant geographical feature in the northeastern part of India.
The Naga hills are a mountain range that extends from the state of Nagaland in India to the Kachin State in Myanmar. These hills are part of the larger Himalayan range and serve as a natural boundary between the two countries. The Naga hills are not only important for their geographical significance but also for their cultural and ecological diversity. They are home to various indigenous communities and a rich variety of flora and fauna.
Understanding the role of the Naga hills as a watershed is crucial because it helps in comprehending the drainage patterns and the flow of water in the region. The Naga hills divide the drainage basins of the two countries, with the water on the Indian side flowing into the Brahmaputra River and the water on the Myanmar side flowing into the Irrawaddy River. This division is significant for both hydrological and geopolitical reasons.
It is important to note that while the Naga hills form the watershed between India and Myanmar, other hill ranges in the northeastern region of India, such as the Garo hills, Khasi hills, and Jaintia hills, are located in different states and do not serve the same function. These other hill ranges are part of the Meghalaya plateau and are not directly involved in the boundary formation between India and Myanmar.
In summary, the Naga hills are the correct answer because they form the natural boundary and watershed between India and Myanmar, dividing the drainage basins of the two countries. This geographical feature is crucial for understanding the hydrological and geopolitical landscape of the region.
