Explain the division and sections of northern plains (5mark question)
Answers
Answer:
Properties are:
(i) The northern plains have been formed from the alluvium deposited by the mountain rivers.
(ii) They are located between the Himalayan rivers in the north and the Peninsular Plateau in the south.
(iii) They turned the soil on the surfaced land fertile for growing a rich harvest of variety of crops. This led to the development of the Indus Valley Civilization.
(iv) They are made up of deposits of alluvium and cover an area of 7 lakh sq. km.
(v) They are densely populated physiographic division of India and are believed to be highly productive in terms of agriculture.
(vi) The North Indian plains have the Indus river system in the west and the Ganga Brahmaputra river system in the East.
(vii) The first include Jhelum, Chenab, Ravi, Beas and Satluj. The Indus flows into the Arabian Sea. The second includes Ganga-Brahamaputra which combines with Meghna at the point when it drains into the Bay of Bengal. They form the world's largest and fastest growing delta. On the basis of difference of relief, they are divided into four parts-Bhabar, Terai, Bhangar and Khadar.
(viii) The northern plain is divided into three sections - Punjab plain, Ganga plain and Brahmaputra plain. The Ganga plain has diverse relief features. It has four belts.
(a) Bhabar is a belt of pebbles extending from 8-16 km in width in which stream disappears.
(b) Terai is a wet, swampy, marshy region with thick forests and wild life.
(c) Bhangar is a terrace-like feature made of old alluvium. It contains calcareous deposits called Kankar.

Answer:
Northern Plains are in India are the most recent landforms. These plains comprise of enormous features. The northern plain is the largest plain covering many rivers that are running from Himalayan mountains. Let us know more about these plains.
Facts about northern plain
The plain has various spectacular features. Let us read about the feature of the plain one by one.
Alluvial deposits
The northern plains are mainly formed by the alluvial deposits.
The northern plain has been formed by the interconnection of the three major river systems. They are the Indus, the Ganga and the Brahmaputra along with their tributaries.
This plain is completely formed of alluvial soil.
The deposition of alluvium in a vast basin lying at the foothills of the Himalaya over millions of years formed this fertile plain.
Area- How it is spread
It stretches its area around 7 lakh sq. km.
The plain is about 2400 km lengthwise and 240 to 320 km breadthwise.
It is a densely populated physiographic division. As per the survey the population maybe around 400 million.
With a rich soil cover equipped with an adequate water supply and favourable climate, it is agriculturally a productive part of India.
Division of the plain
The Northern Plain is mainly divided into three sections.
The Western part of the Northern Plain is referred to as the Punjab Plains. It is formed by the Indus and its tributaries, the larger part of this plain lies in Pakistan.
The Indus and its tributaries are the Jhelum, the Chenab, the Ravi, the Beas and the Satluj all originate in the Himalaya.
The Ganga plain broadly extends between Ghaggar and Teesta rivers.
The plain spreads over the northern states of Haryana, Delhi, U.P., Bihar and partly Jharkhand.
The Ganga plains also extend towards Bengal towards the eastern region.
Further towards the east, in Assam lies the Brahmaputra plain.
The northern plains are called as flatlands with no variations in its relief. However, this is not completely true. These vast plains also have diverse relief features.
Variations in relief features
According to the variations in relief features, the Northern plains can be categorised in four segments or regions.
The rivers, that are descending from the mountains, deposit pebbles in a narrow belt of around 8 to 16 km in width lying parallel to the slopes of the Shiwaliks. This region is called bhabar. All the streams disappear or vanish in this bhabar belt.
In the southern part of this belt, the streams and rivers re-emerge and create a wet, swampy and marshy region called terai. This was once a thickly forested region, full of wildlife.
