Question

give an account of Northern plain of India?

Answer 1

(a) The Himalayan uplift out of the Tethys sea and subsidence of the Northern flank of the peninsular plateau resulted in the formation of a large basin. In course of time, this depression gradually got filled with deposition of sediments from rivers flowing from the mountains in the north and led to formation of the fertile Northern plains. (b) It spreads over an area of 7 lakh sq km. The plain is about 2400 km long and 240-230 km broad. (c) It is a densely populated and an intensively cultivated area. (d) With its adequate water supply and favourable climate, it is agriculturally a very productive part of India. (e) The Northern plains are broadly divided into 3 sections. (f) The Western part of the Northern plains is called the Punjab plains, formed by the Indus and its tributaries. (g) Ganga plain extends between the Ghaggar and the Teesta rivers, spread over the states of Haryana, Delhi, UP, Bihar and West Bengal. (h) The Brahmaputra Plain to the East of the Ganga plains lies. The Brahmaputra plain covering the areas of Assam and Arunachal Pradesh.

Answer 2

Answer :

The northern plain has been formed by the interplay of the three major river systems, namely– the Indus, the Ganga and the Brahmaputra along with their tributaries. This plain is 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. It spreads over an area of 7 lakh sq. km. The plain being about 2400 Km long and 240 to 320 Km broad is a densely populated physiographic division. With a rich soil cover combined with adequate water supply and favourable climate 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 known as distributaries. The Northern Plain is broadly divided into three sections. The Western part of the Northern Plain is referred to as the Punjab Plains. Formed by the Indus and its tributaries, the larger part of this plain lies in Pakistan. The Indus and its tributaries–the Jhelum, the Chenab, the Ravi, the Beas and the Satluj originate in the Himalaya. This section of the plain is dominated by the doabs.
