Ganga Brahmaputra Delta

  • By the time a river reaches its end, it has lots of sediment. This sediment settles down and makes the river split into many channels or distributaries. 
  • In between these distributaries, triangular-shaped islands are formed. 
  • These are called Delta because they resemble a triangle(Δ). 
  • The Ganga- Brahmaputra delta is called as Sunderban.
