Movement in the air of a cricket ball can be caused both with spin as well as by the very position of the seam. The finest explanation of the phenomenon of movement in the air that I have ever come across is in Bradman's Art of Cricket, easily the finest cricket coaching book. The write up is pretty long running into six-seven large pages. I will try and scan them to put them here.
