Question

Answer 1

Instructions:

• Give a small introduction to northern plains
• Explain the northern plains

Solution:

The northern plains have been formed by the drainage deposition of the three major river systems— the Indus, the Ganga, and the Brahmaputra along with their tributaries.

Formation -
This plain is mainly formed of alluvial soil.
The deposition of alluvium by the three major river systems in the foothills of the Himalayas over millions of years resulted in the formation of these fertile plains.

​Extent -
The northern plains extend over a vast area of 7 lakh square. km. The northern plains are, 2400 km long and 240 to 320 km wide. The northern plains have densely populated physiographic divisions. Due to rich alluvium deposits and adequate water supply with a favourable climate, agricultural activities are mainly concentrated in this region.

​Division of the northern plains -
1) Punjab plains: The western part of the northern plains is formed by the depositions of Indus and its tributaries. The majority of this region lies in Punjab. Hence, it is also referred to as Punjab Plains.
2) Ganga plains: The Ganga Plains stretch mainly between two important rivers, Ghaggar and Teesta. They cover mostly the regions of Haryana, Delhi, Uttar Pradesh, Bihar, and partly Jharkhand.
3) Brahmaputra plains: The Brahmaputra plains are mainly in Assam. They are formed by the depositions of the sediments brought by the Brahmaputra and its tributaries.
