Recent observations have revived new interest in the kinematical and dynamical interpretation of large scale warps in galaxy disks. A simple excitation mechanism is outlined for warping structures which is based on the transfer of angular momentum between the flat and the spheroidal components of a disk galaxy. A moderate spheroidal (bulge-halo) component is sufficient to provide the additional amplification needed by Hunter and Toomre in order to interpret the warps in the Milky Way as due to the passage of the Large Magellanic Cloud. In addition, a new mechanism (similar to that successfully used for the spiral structure problem) is suggested which may give self-excited and self-sustained warping modes; these modes may be helpful in understanding the observations in galaxies without close companions. It is argued that warps may provide important clues as to the size and structure of galaxy halos.
