Q5. Give an account of the Northern Plains of India.
Ans:

  • The Northern Plains have been formed from the alluvium that the mountain rivers deposited here.
  • It led to the soil turning fertile on the surface for growing a rich harvest of various crops. This also resulted in the development of the Indus River Valley Civilisation.
  • The rich soil was further aided by a favourable climate and constant water supply from the rivers. Between the mouths of the Indus and the Ganga-Brahmaputra, the North Indian Plain covers a distance of 3200 km.
  • The North Indian Plains have the Indus River system in the west and the Ganga- Brahmaputra river system in the east.
  • The first includes Jhelum, Chenab, Ravi, Beas, and Satluj. The Indus flows into the Arabian Sea.
  • The second includes Ganga, its tributaries, and the Brahmaputra, which combine as Meghna as they drain into the Bay of Bengal.
  • They form the world’s largest and fastest-growing delta.
