What is the reason for the disappearance of many rivers in Bangladesh?

Think it through first, then pick an option.

  1. a landslides on hills
  2. b building dams
  3. c earthquake
  4. d deposit of silt
Answer and explanation

Correct answer: d deposit of silt

The book says silt fills the river bed, shoals form and many rivers disappear.

Why the other options are wrong

  • a landslides on hills: Landslides are not given in the book as a cause of rivers disappearing.
  • b building dams: Dams reduce flow, but on rivers disappearing the book speaks of silt deposit and shoals.
  • c earthquake: An earthquake created the Jamuna; it is not given as the cause of rivers disappearing.
