Question

Air moves from low pressure to high pressure.
A. True
B. False

Answer 1

Hint: - In low pressure areas when the wind blows anti clockwise, cyclones are formed.
- The region on the earth surface where large compounds of the air have a uniform temperature And humidity are called source regions. In this region, air masses can fester and stop flowing. The main source region is - the high pressure belts in the subtropical region and around the region in poles.

Complete Answer:
Low Pressure area: In a low pressure area the magnitude of pressure is much less than at the centre than that of its surroundings. The winds blow into the area of low pressure where the air in the atmospheric layers rises. The water vapour condenses and also precipitates as the air rises. The winds in low pressure zones blow anticlockwise to the north of the equator and clockwise to the south of the equator owing to the Coriolis influence.

High pressure area: In a high pressure area the centre has more pressure than that of its surrounding. In a high pressure region, the wind blows clockwise at the north of the equator and anti-clockwise at the south end of the equator. This is an anticyclonic flow. Air from the higher region in the atmosphere sinks downwards and thus marks a high pressure area.

It creates a low pressure zone as hot air rises, and it creates a high pressure zone as cold air falls. The wind is produced by air that travels horizontally between high and low pressure zones. When there is a larger pressure differential between the pressure zones, the wind travels quicker and it travels from an area of high pressure to low pressure. Due to air circulation between high and low intensity, the wind belts that influence the regional atmosphere are formed.

Thus we can conclude that the above statement is false and the correct answer is B.

Note: - Typhoon Tip was the largest cyclone ever in the record. The cyclone continued for 20 days from 4 October 1979 to 24 October 1979. The typhoon with the diameter of 2220 kilometres and with the highest speed recorded of 360km/h recorded 99 fatalities and affected the major areas of the Philippines and Japan.
- The great Bhola cyclone is considered as one of the deadliest cyclones in world history. This cyclone emerged in the Bay of Bengal and this cyclone completely devastated Bangladesh. The cyclone destroyed 85% of land area and recorded 300,000 to 500,000 deaths.
