Physical Features of India
The northern Plain
ORTHERN
PLAINS

The Indian desert lies towards the western margin of the Aravali hills.

It is an sandy plain covered with sand dunes. This region receives very low rainfall below 150mm per year. It has arid climate with low vegetation cover.

Streams appear during the rainy season. Eg:luni only largest river.

Barchans (cresent shaped dunes) cover larger areas but longitudinabarl dunes are prominent near indo-pakistan..

Barchans are found in jaisalmer


Deserts..

The largest part of the northern plain is formed by older alluvium. They lie above the flood plains of rivers and present a terrace like feature. This is known as bhangar.

The soil in this region contains calcareous deposits of the flood plains are called kankar.

The newer, younger deposits of the flood plains are called khadar.

They are renewed almost every year and so are fertile,thus,ideal for intensive agriculture.

The rivers coming from northern mountain are involved in depositional work, In the lower course, due to the gentle slope, the velocity of the river descreases which results in the formation of riverine islands.

DID YOU KNOW?
Majuli, in the Brahmaputra River is the largest inhabited riverine island in the world

The Northern Fertile Plain lies to the south of Himalayan

Region. These plains have been formed due to the interplay

of 3 major rivers, namely- THE INDUS, THE GANGA & THE

BRAHMAPUTRA. It is a vast plain and level land between the

Himalayas in the North and Deccan Plateau in the South. From

Punjab in the West to Assam in the East, this plain is about 2400

km. Because of its rich soil cover, adequate water supply and

favorable climate conditions, it is agriculturally a very productive

part of India.
The rivers in their lower course split into numerous channels due to the deposition of silt.

These channels are know as disturbutaries.

The Northern plains are broadly divided into three sections-
The western part of the northern plains is referred tohe Punjab Plains.{Indus and its tributies}

The larger part of the plain lies in Pakistan

Indus and its tributies- Jhelum, the Chenab, the Beas, teh Setluj [orginated in himalayas and the Ravi .
This section of the plain is dominated by the doabs
The northern plains are vast plains with diverse relief features.
The northern plains can be divided into 4 parts according the relief features

Bhabar
The rivers and streams after coming down from the mountains, deposit pebbles in a narrow belt .
This belt is called the Bhabar and it is 8-16km in width.
The lye parallel to the Shiwaliks.

TeraiAll streams and rivers disappear in the bhabar belt.
Towards the south of this belt the straema and rivers re-emerge.
This creates a wet, swampy and marshy region .
This region is called the terai.

Uses of the Terai
The terai was a thickly foerested area with lots of wildlife animals.
For the migrants from Pakistan to settle in India, this land was cleared to create agricultural land.
