Explanations:The Brahmaputra River is one of the major rivers in South Asia, originating from the Chemayungdung glacier in the Himalayas, located in the Tibet Autonomous Region of China. It is known by different names in different regions. In Tibet, it is called the Yarlung Tsangpo, and after entering India, it is known as the Brahmaputra.
The river flows through the eastern part of the Tibetan Plateau and then enters India through the state of Arunachal Pradesh. The entry point is near the town of Sadiya, where the river forms a significant part of the international border between India and China. The river then flows through the state of Arunachal Pradesh for a considerable distance before entering Assam.
Once in Assam, the Brahmaputra becomes a major river system, contributing significantly to the geography and economy of the region. It is known for its wide and deep channel, which makes it an important waterway for transportation and trade. The river also plays a crucial role in the agricultural economy of the region, providing fertile alluvial soil and water for irrigation.
After flowing through Assam, the Brahmaputra enters Bangladesh, where it merges with the Ganges to form the world's largest delta, the Sundarbans. This delta is a UNESCO World Heritage site and is known for its unique ecosystem and biodiversity.
Understanding the geographical entry point of the Brahmaputra River is important for students of geography and those preparing for competitive examinations that test knowledge of Indian geography. It is essential to remember that the river enters India through Arunachal Pradesh and not through other states like Assam, Tripura, or Bihar.
