Case Study Questions on Drainage Class 9

Questions

Passage 1:

Read the following passage and answer the questions:

Apart from originating from the two major physiographic regions of India, the Himalayan and the Peninsular rivers are different from each other in many ways. Most of the Himalayan rivers are perennial. It means that they have water throughout the year. These rivers receive water from rain as well as from melted snow from the lofty mountains. The two major Himalayan rivers, the Indus and the Brahmaputra originate from the North of the mountain ranges. They have cut through the mountains making gorges. The Himalayan rivers have long courses from their source to the sea.

They perform intensive erosional activity in their upper courses and carry huge loads of silt and sand. In the middle and the lower courses, these rivers form meanders, ox-bow lakes, and many other depositional features in their floodplains. They also have well-developed deltas.

Q. 1. Mention any two features of the Himalayan rivers.

Ans. The two features of the Himalayan rivers are:

(i) They have long courses from their source to the sea.

(ii) These rivers perform both erosional as well as depositional activities.

Q. 2. Why are most of the Himalayan rivers perennial?

Ans. Most of the Himalayan rivers are perennial because they have water throughout the year. They receive water from rain as well as from melted snow from the lofty mountains.

Q. 3. How do the Himalayan rivers form depositional features?

Ans. When Himalayan rivers reach the plains, the slope of the land is much less, slowing down the river and making them deposit much of the silt they have accumulated. So, the Himalayan rivers form depositional features in their lower courses.

The river system of an area is called its drainage. The area drained by a single river system is called drainage basin. An elevated area that divides two drainage basins from each other is known as a water divide. The Indian river systems are divided into two major groups: (1) Himalayan rivers, and (2) Peninsular rivers. These two river systems, i.e., Himalayan and Peninsular river systems originate from two different physiographic regions of India.

The river Yamuna originates from the Yamunotri Glacier in the Himalayas and flows parallel to the Ganga. It meets the Ganga at Allahabad.
