Answer:
B
Explanation:
The wind is caused by differences in atmospheric pressure. When a difference in atmospheric pressure exists, air moves from the higher to the lower pressure area, resulting in winds of various speeds. On a rotating planet, air will also be deflected by the Coriolis effect, except exactly on the equator.
The primary cause of wind ; ( B ) Air pressure differences
The difference in air atmospheric pressures leads to the movement of air across the different pressures ( from higher to lower pressure areas ) within the atmosphere.
The speed of air movement determines the wind speed and which is the primary cause of wind. Wind speeds and pressures are measured with help of an anemometer.
Hence we can conclude that the primary cause of wind is Air pressure differences
