Question
How many pressure belts are there on the surface of the earth? Discuss them, in brief.
Answer
There are three pressure belts on the surface of the earth – the Equatorial Low Pressure Belt, the Subtropical High Pressure Belts, and the Polar High Pressure Belts.
- Equatorial Low Pressure Belt: It is also known as the Doldrums. This belt is characterized by low pressure, convergence of trade winds, and ascending air. The intense heating of the equator results in warm air rising and spreading towards the poles.
- Subtropical High Pressure Belts: These belts are also known as the Horse Latitudes. They are characterized by high pressure, descending air, and dry weather conditions. These belts are located around 30 degrees north and south of the equator.
- Polar High Pressure Belts: These belts are characterized by high pressure, descending air, and extremely cold weather conditions. These belts are located around the poles.
