(i) This division lies between Himalayan Mountains in the north and the Peninsula in the south.
(ii) Similarly, it extends from Rajasthan and Punjab in the west to Assam in the east.
(iii) It is mostly a flat low lying area.
(iv) The North Indian Plains are divided into two parts. The part lying to the east of the Aravalis is the basin of the river Ganga and is therefore known as the Ganga Plains. It slopes eastward.
(v) Most of the Indian state of West Bengal and Bangladesh together constitute the delta of Ganga-Brahmaputra system. It is known as the Sunderbans. It is considered to be the world’s largest delta.
(vi) The western part of the North Indian Plains is occupied by desert known as the Thar Desert or Marusthali. Most of Rajasthan is occupied by this desert.
(vii) To the north of the desert lie the plains of Punjab.
(viii) This region is spread to the west of Aravalis and Delhi ranges. These plains have formed as a result of the depositonal work by river Satluj and its tributaries. The slope of the plains is towards the west.
Because the soil here is very fertile, agriculture is largely practised in this region.
