Question

The wind blows _____.

• A. when there is no change in temperature
• B. when there is a pressure difference
• C. when the region has increased pressure
• D. when the region has no change in pressure

Answer 1

The correct option is B

when there is a pressure difference

The wind blows because of differences in air pressure from one location to another. Wind blows from areas of high pressure towards areas of low pressure. If the high pressure area is very close to the low pressure area, or if the pressure difference is very great, the wind can blow very fast.
