Which term refers to air movement resulting from horizontal pressure differences, commonly described simply as wind?

• A. Wind
• B. Buys Ballot's Law
• C. Coriolis force
• D. Friction

Answer: (A)

Air movement caused by horizontal pressure differences is wind. This happens because a pressure gradient force pushes air from regions of high pressure toward regions of low pressure, starting the horizontal flow we experience as wind. In the real atmosphere, how fast and in what direction wind blows is shaped by a balance of forces: the pressure gradient force drives it, the Coriolis effect deflects it due to Earth's rotation, and friction with the surface slows and redirects it near the ground. Buys Ballot's Law describes how wind direction relates to the position of high and low pressure systems and helps deduce weather patterns, but it’s not the term for the air movement itself. The Coriolis force is the deflection effect that alters the path of the moving air, not the motion by itself. Friction is the surface force that slows wind and changes its direction near the ground. The actual term for the air movement is wind.
