Question

Mention the three stages of the river. Name one landform associated with each stage.

Answer 1

The three stages of a river are:

1. Upper Course (Youthful stage): The river is in the mountains, flowing fast with high erosion.
   • Landform: Valley (V-shaped valley formed by vertical erosion) or Waterfall.
2. Middle Course (Mature stage): The river enters the plains, slows down, and both erosion and deposition occur.
   • Landform: Meanders or Ox-bow Lake.
3. Lower Course (Old stage): The river approaches the sea with low velocity; deposition is dominant.
   • Landform: Delta or Estuary.
