Question

The velocity of winds is governed by ______________.

• A. temperature
• B. rotation of the Earth
• C. pressure gradient
• D. All the above

Answer 1

The correct option is C pressure gradient

• Winds originate due to the pressure gradient i.e. winds travel from higher pressure region to the lower pressure region. The more the pressure gradient, the greater will be the wind speed and vice-versa. Hence option C is correct.
• Rotation of the earth may affect wind direction eg Ferrel's law, but they do not govern the wind speed.
