The correct answer is: (b) Tibet is cold and dry
Explanation:
The Brahmaputra River originates in the Tibetan Plateau near Lake Mansarovar and flows through Tibet before entering India and Bangladesh. While in Tibet, the river carries less silt and water due to the following reasons:
Cold and Dry Climate – Tibet has a cold desert climate with low rainfall, meaning there is less erosion and less water flowing into the river.
Limited Tributaries – In Tibet, the Brahmaputra does not receive many tributaries, so it remains shallow and slow-moving.
Glacial Source – The river is mainly fed by melting glaciers, which provide a steady but low volume of water in Tibet.

The correct answer is: (c) The Himalayan rivers have short courses from their source to the sea
Explanation:
Himalayan rivers have long courses, not short ones. They originate in the Himalayas and travel thousands of kilometers before reaching the sea.
(a) Himalayan rivers are perennial – Correct because they receive water from glaciers and rainfall, making them flow throughout the year.
(b) They have water throughout the year – Correct, as they are fed by melting snow and monsoon rains.
(d) They perform intensive erosional activity in their upper courses and carry huge loads of silt – Correct, because their steep gradients in the upper course cause strong erosion, leading to high sediment transport.
(c) The Himalayan rivers have short courses from their source to the sea – Incorrect, as rivers like the Ganga, Brahmaputra, and Indus have very long courses before reaching the sea.
Thus, the correct answer is:
(c) The Himalayan rivers have short courses from their source to the sea This question related to Chapter 3 Social Science Class 9th NCERT. From the Chapter 3 Drainage. Give answer according to your understanding.
