known as the water divide. Ambala is located on the water divide between the Indus and the Ganga
river systems
(ii) Which is the largest river basin in India?
A. The Ganga basin is the largest basin in India.
(iii) Where do the rivers Indus and Ganga have their origin?
A. The headwaters of the Ganga called the ‘Bhagirathi’ is fed by the Gangotri Glacier and joined by the

Tibet so it has less silt there. On the other hand, this very river when enters India it passes through
such a region which receives heavy rainfall. As such in India, it carries a large volume of water and a
larger amount of silt.
(vi) Which two Peninsular rivers flow through trough?

4. Discuss the significant difference between the Himalayan and the Peninsular rivers.
A. Differences between the Himalayan Rivers and The Peninsular or Deccan Rivers.
1. The Himalayan rivers rise in the snow-covered mountains as such they flow throughout the
year. The mountains in which the Deccan rivers rise are not snow-covered. Hence they dry up
in summer.
2. The Himalayan rivers flow in leveled Northern Plains. Therefore, they are quite useful for
navigation and irrigation. The Peninsular rivers flow on the uneven rocky surface. Therefore
they are neither navigable nor useful for irrigation.
3. The Himalayan rivers bring with them fertile alluvium which they deposit in the Indo-Gangetic
Plains. The Peninsular rivers do not bring with them enough alluvium. As the current is swift so
the deposition activity is negligible.
4. Canals have been dug to use the water of these rivers for irrigation. As the terrain is rocky and
the banks of these rivers are high, canals cannot be dug. However, dams are built to store the
floodwater for irrigation with the help of small channels
5. Many important towns and centres of trade are situated on the banks of these rivers. Very few
important towns and centres of trade are situated on the banks of these rivers.
6. The porous soil absorbs a lot of water, which is later on used as groundwater by digging wells
and tube wells for domestic and irrigation purposes. The rocky soil does not absorb any water.
Hence no wells can be dug. All the water flows down the sea at one and the same time.
5. Compare the east flowing and the west flowing rivers of the Peninsular plateau.
A. East Flowing Rivers
The Mahanadi, the Godavari, the Krishna, and the Kaveri are the main east flowing rivers of
Peninsular India. These rivers drain in the Bay of Bengal. These rivers make deltas at their mouth
West Flowing Rivers.
These rivers have a developed tributary system. Their tributaries are comparatively large in size.
These rivers flow through not very deep channels.
The Narmada and the Tapi are the main west-flowing rivers of Peninsular India. These rivers drain in
the Arabian Sea. These rivers enter the sea through estuaries. These rivers are devoid of developed
tributary system. Their tributaries are quite small in size. These rivers flow in a trough or a funnel-like
narrow but deep channel.
6. Why are rivers important for the country’s economy?
A. Rivers have been of fundamental importance throughout human history. Water from the rivers is a
basic natural resource, essential for various human activities. Therefore, the riverbanks have attracted
settlers from ancient times. These settlements have now become big cities. Make a list of cities in your
state, which is located on the bank of a river. Using rivers for irrigation, navigation, hydropower
generation is of special significance – particularly to a country like India, where agriculture is the
major source of livelihood of the majority of its population.
Summary of Drainage
The phrase drainage refers to a region’s river system. A drainage basin is an area drained by a single river basin. ‘Contemporary India’ is the third chapter in the NCERT Class 9 Geography books. I’m interested in India’s drainage system. The following issues have been covered in depth in this chapter:
- The Rivers of the Himalayas
- The System of the Indus River
- The Ganges River Basin
- The Brahmaputra River System is a river system in India.
- The Peninsular Rivers
- Narmada Basin
- Tapi Basin
- Godavari Basin
- Mahanadi Basin
- Krishna Basin
- Kaveri Basin
- Lakes
- The Economic Impact of Rivers
Students will also learn about the causes of river contamination and the consequences for society. Concerns about rising river pollution will also teach children how conserving resources such as water bodies may aid in the creation of a healthier living environment.
Students can use the NCERT Solutions for Class 9 Social Science to find answers to questions from the textbooks in Geography, History, Political Science, and Economics.
