Option 1 : Sub-tropical high pressure belt

The correct answer is option 1) i.e.Sub-tropical high-pressure belts.

  • On the earth’s surface, there are seven pressure belts.
  • Equatorial Low-Pressure Belts -It extends from 0 to 5° North and South of Equator. It is thermally induced. It is characterized by low and feeble wind because of the convergence North-east and South-east trade winds. Because of these calm conditions, it is also known as a belt of calm or doldrums.

  • Sub-tropical high-pressure belts - It extends about 30° to 35° in both hemispheres where the ascending equatorial air currents descend. This area is thus an area of high pressure. It is also called as the Horse latitude.

  • Sub-Polar low-pressure belts -  It extends about 60° to 65° in both hemispheres. It is a dynamically induced low-pressure belt.

  • Polar High-pressure belts - High pressure persists throughout the year because of the prevalence of low temperatures throughout the year.
