Explanation: The Naga hills are a significant geographical feature in the northeastern part of India, forming a natural boundary with Myanmar. The term "watershed" refers to a ridge of land that separates waters flowing to different rivers, basins, or seas. In the context of the Naga hills, this means that the mountains serve as a natural divide, influencing the flow of rivers and the climate of both India and Myanmar.
The Naga hills are part of the larger Himalayan mountain system, which extends across several countries in South and Southeast Asia. However, the Naga hills specifically are located in the northeastern part of India, primarily in the state of Nagaland, and extend into Myanmar. This mountain range is not only a geographical boundary but also a cultural and ecological boundary, as it influences the climate, biodiversity, and human settlements on both sides.
The misconception that the Naga hills might form the watershed between India and other countries like China, Bhutan, or Bangladesh arises from a lack of specific knowledge about the geographical boundaries in the northeastern part of India. The Himalayas form the primary watershed between India and China, while the Ganges-Brahmaputra delta forms the watershed between India and Bangladesh. Bhutan, located to the north of India, is separated from India by the Himalayas as well.
Understanding the specific role of the Naga hills in forming the watershed between India and Myanmar is crucial for comprehending the geographical, ecological, and cultural dynamics of the northeastern region of India. This knowledge is essential for students preparing for competitive examinations that cover geography and regional studies, as it helps in understanding the complex interplay of geographical features and their impact on the environment and human societies.
