What is wind?
What will be an ideal response?
Wind is the motion of gas molecules in the atmosphere that is caused by atmospheric convection and variations in atmospheric pressure. Warm air has a lower density than cool air and humid air is less dense than dry air. Higher density air sinks close to the surface, producing high pressure at the surface, and displaces lower density air upward to produce low pressure at the surface. Air moves from regions of high pressure toward regions of low pressure. Wind is the motion of air sinking and rising because of density differences, and moving from areas of high pressure toward low pressure.
