Question

Choose the correct statement from the following.

• A. High-speed winds are accompanied by reduced air pressure.
• B. High-speed winds are accompanied by increased air pressure.
• C. Change in pressure does not affect the wind velocity.
• D. Humidity can change the velocity and direction of wind.

Answer 1

The correct option is A High-speed winds are accompanied by reduced air pressure.

Air flows from high pressure to low pressure to occupy the low pressure region, which results in an increase in the speed of the winds. Thus we can say that high-speed winds are accompanied by reduced air pressure. At the same time, humidity cannot change the velocity and direction of wind. Also, it is clear that pressure differences affects wind velocity and hence we cannot say that change in pressure does not affect the wind velocity.
