With reference to river Teesta, consider the following statements :
- 1.The source of river Teesta is the same as that of Brahmaputra but it flows through Sikkim.
- 2.River Rangeet originates in Sikkim and it is a tributary of river Teesta.
- 3.River Teesta flows into Bay of Bengal on the border of India and Bangladesh.
Which of the statements given above is/are correct ?
Show answer
Answer: B. Statement 1 is wrong: the Teesta rises from Tso Lhamo lake and the Teesta Khangse glacier in north Sikkim. The Brahmaputra rises from the Chemayungdung glacier near Mansarovar in Tibet. Statement 2 is correct: the Rangeet rises from the Rathong glacier in West Sikkim and joins the Teesta near the Sikkim-West Bengal border. Statement 3 is wrong: the Teesta enters Bangladesh and joins the Brahmaputra (Jamuna). It does not flow into the Bay of Bengal on the border. So only 2.
Watch for: Watch for statement 3: the Teesta does end up in the Bay of Bengal, but only through the Brahmaputra inside Bangladesh.
Why the other options are wrong
- A. Wrong because the Teesta's source is in Sikkim, not shared with the Brahmaputra, and it joins the Brahmaputra rather than the sea.
- C. Wrong because the Teesta joins the Brahmaputra in Bangladesh, not the Bay of Bengal.
- D. Wrong because statements 1 and 3 are false.
