Which of the following pressure belts is called ‘doldrum'? I. Equatorial low-pressure belt II. Polar high-pressure belt 

Which of the following pressure belts is called ‘doldrum'? I. Equatorial low-pressure belt II. Polar high-pressure belt  Correct Answer Only I

The correct answer is an Equatorial low-pressure belt.

Key Points

  • The equatorial low-pressure belt lies between 10° North and 10° South.
  • Equatorial low-pressure belt is called 'Doldrums' because of the extremely calm air movements.
  • The position of the belt varies with the apparent movement of the Sun.
  • This belt happens to be the zone of convergence of trade winds from two hemispheres from subtropical high-pressure belts.
  • This belt is also known as the Inter-Tropical Convergence Zone (ITCZ).

 Thus, we can say that the Equatorial low-pressure belt is called 'Doldrum'.

Additional Information

  • Polar high-pressure belts lie around the poles between 80° North and 90° South latitudes.
