Riverine islands are formed in the lower courses due to fluvial erosion activity in the upper reaches of the Himalayan Mountains. 3. Brahmaputra plains are known for their riverine islands and sand bars. Which of the statements given above is/are correct?

The correct answer is 1, 2 and 3.

Key Points

  • All the statements given are correct.
  • The rivers coming from northern mountains are involved in depositional work.
  • In the lower course, due to gentle slope, the velocity of the river decreases which results in the formation of riverine islands.
  • Due to Erosion activity in the upper reaches of Himalayan mountains, rivers carry the alluvial sediments.
  • When deposited in the floodplains, forms the riverine islands.
