The Himalayan Rivers
हिमालयी नदियाँ
In Class 9 Geography, this topic from the chapter “Drainage” introduces the Himalayan river systems, especially the Indus, Ganga and Brahmaputra. Students learn how these rivers are fed by glaciers, snow and rainfall, making them largely perennial, and trace their courses, major tributaries and drainage patterns. The topic also explains how Himalayan rivers shape deep gorges, valleys, meanders, floodplains and deltas, while supporting farming, settlements and ecosystems. It highlights their economic importance as well as the challenges of floods, erosion and changing water conditions.

Which is one main source of water for the Himalayan rivers?
Correct answer: B
Himalayan rivers receive water from more than one source. Snow and glaciers stored high in the mountains melt seasonally and feed streams and rivers, especially during warmer months. Rainfall, including monsoon rain, is another important source and can increase river discharge greatly. Because glaciers and snow continue to provide meltwater while rainfall varies, many Himalayan rivers are perennial, meaning they carry water through much of the year.
Option B is correct because glaciers and melting snow are a major source of Himalayan river water. Option A is wrong because desert rainfall is not the defining source, and the word “only” also excludes other sources. Sea waves do not supply these inland rivers, and underground oil is not water. The most complete school-level statement would mention both snow or glaciers and rainfall; among the given choices, “glaciers and melting snow” is the only suitable answer.
Which is included among the major Himalayan river systems of India?
Correct answer: C
The Indus is a major Himalayan river system. Exam tip: remember Indus Ganga and Brahmaputra together.
View question detailsWhat type of river system is the Ganga river system considered?
Correct answer: D
The Ganga is a major river system rising from the Himalayas. Exam tip: place Ganga among Himalayan rivers.
View question detailsThe Brahmaputra river system belongs to which group?
Correct answer: A
The Brahmaputra is part of the Himalayan river system. Exam tip: remember its link with north eastern India.
View question detailsWhat kind of valleys do Himalayan rivers form in their upper courses?
Correct answer: B
In the upper course steep slopes help rivers cut deep valleys. Exam tip: connect upper course with erosion.
View question detailsWhy is erosion high in the upper course of Himalayan rivers?
Correct answer: C
A steep slope gives the river fast flow and more cutting power. Exam tip: remember the link between slope and erosion.
View question detailsWhat do Himalayan rivers deposit after entering the plains?
Correct answer: D
When slope decreases in the plains rivers deposit alluvium. Exam tip: understand the cause of alluvial plains.
View question detailsThe Ganga plain is mainly formed by what?
Correct answer: A
The Ganga and its tributaries formed a vast alluvial plain. Exam tip: connect river deposition with plain formation.
View question detailsHow do Himalayan river channels flow in the plains?
Correct answer: B
In plains low slope makes rivers form meanders. Exam tip: remember low gradient and bends together.
View question detailsWhy does the possibility of floods increase in the plains of Himalayan rivers?
Correct answer: C
Slow flow and large water volume in plains can cause floods. Exam tip: remember the plains flood connection.
View question detailsWhy is the water of Himalayan rivers useful for agriculture?
Correct answer: D
Perennial water and alluvial plains support farming. Exam tip: study irrigation and fertile soil together.
View question detailsThe origin region of the Indus river system is linked with what?
Correct answer: A
The Indus system is linked with high Himalayan regions. Exam tip: remember its mountainous source region.
View question detailsBy which name is the main stream of the Ganga famous in the plains?
Correct answer: B
After leaving the mountains it flows in the plains as the Ganga. Exam tip: note sections where names are used.
View question detailsYamuna is a major tributary of which river system?
Correct answer: C
The Yamuna is one of the major tributaries of the Ganga river system. It rises from the Yamunotri Glacier and joins the Ganga at Prayagraj. The Narmada and Krishna are Peninsular river systems, so they are not associated with the Yamuna. Exam tip: remember the Yamuna–Prayagraj–Ganga confluence link.
View question detailsGhaghara Gandak and Kosi are associated with which river system?
Correct answer: D
They are counted among major tributaries of the Ganga. Exam tip: remember tributaries coming from the north.
View question detailsThe Kosi river is often associated with which problem?
Correct answer: A
Kosi is known for floods and course shifting. Exam tip: remember it in connection with floods.
View question detailsThe Brahmaputra mainly flows through which region in India?
Correct answer: B
In India the Brahmaputra is a major river of Assam. Exam tip: remember the Brahmaputra Assam link.
View question detailsWhy does the Brahmaputra carry a large amount of water?
Correct answer: C
Heavy rainfall in the north east and Himalayan sources increase its water. Exam tip: mention both rainfall and sources.
View question detailsWhat is the usual length of Himalayan rivers?
Correct answer: D
Himalayan rivers rise in mountains and flow far across plains. Exam tip: remember their long courses.
