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.

Antecedent rivers maintain their course even after uplift. Exam tip: connect Himalayan gorges with this idea.
View question detailsHimalayan rivers receive water from glaciers and rainfall. Exam tip: understand perennial flow through two water sources.
View question detailsTheir origin and upper flow are related to the Himalayas. Exam tip: connect source region with river classification.
View question detailsIn the upper Himalayas the river cuts downward on steep slopes. Exam tip: connect deep valleys with vertical erosion.
View question detailsJhelum Chenab Ravi Beas and Sutlej are linked with the Indus system. Exam tip: remember them with the Punjab region.

View question detailsBhagirathi rises from Gangotri Glacier and meets Alaknanda at Devprayag. Exam tip: remember both source and confluence.
View question detailsBhagirathi and Alaknanda meet at Devprayag. Exam tip: keep Devprayag and Prayagraj separate.
View question detailsAfter Haridwar the slope decreases and the river takes a plain course. Exam tip: remember the effect of entering plains.
View question detailsOption A is correct: the Yamuna is a major right-bank tributary of the Ganga and joins it at Prayagraj, forming the well-known Sangam with the Ganga and the mythical Saraswati. A tributary flows into a larger river, whereas a distributary branches away from one. Yamuna is not connected to the Brahmaputra, Narmada or Luni systems in the ways described by the other options.
View question detailsPrayagraj in Uttar Pradesh is known for the confluence of the Ganga and Yamuna; traditionally, the invisible Saraswati is also believed to join there. In contrast, the Bhagirathi and Alaknanda meet at Devprayag in Uttarakhand, and the river is called the Ganga after this confluence. Option B incorrectly reverses the two confluences. Exam tip: remember Devprayag as the point from which the river is known as the Ganga.
View question detailsRivers like Ghaghara Gandak and Kosi bring Himalayan water and sediments. Exam tip: link floods with tributaries.
View question detailsThe Kosi carries a very large sediment load from the Himalayas into the flat, low-gradient plains of Bihar. Deposition raises or blocks parts of its channel, causing the river to shift its course. Sea tides do not cause the Kosi's course changes in its Himalayan or plain reaches. Exam tip: remember the Kosi as the “Sorrow of Bihar,” associated with floods and channel shifting.
View question detailsThe Son joins the Ganga system from the southern side. Exam tip: keep northern and southern tributaries separate.
View question detailsChambal is connected to the Ganga system through Yamuna. Exam tip: understand indirect river links.
View question detailsBrahmaputra is called Tsangpo in Tibet Dihang in Arunachal and Jamuna in Bangladesh. Exam tip: remember regional names.
View question detailsIn Assam Brahmaputra forms a wide channel with high water and sediment. Exam tip: connect floods with both water and sediment.
View question detailsDeposition in the delta can divide the main stream into many distributaries. Exam tip: connect distributaries with the final river course.
View question detailsIndus Ganga and Brahmaputra systems formed northern plains by depositing sediments. Exam tip: connect plain formation with deposition.
View question detailsBhangar is older alluvium and Khadar is newer alluvium. Exam tip: remember the difference between old and new deposits.
