How is the said flood plain formed?
Think it through first, then pick an option.
- a By soil carried by floods settling down
- b By interglacial meltwater
- c By an earthquake

Answer and explanation
Correct answer: a By soil carried by floods settling down
The book says silt carried with flood water settled year after year and formed the flood plain.
Why the other options are wrong
- b By interglacial meltwater: This is the guessed cause of the Pleistocene terraces.
- c By an earthquake: The flood plain was not formed by an earthquake; silt formed it.
- d When the Himalayas rose: The Tertiary hills were formed at that time.
