Energy is moving, not water. orbital motion. energy is transferred via circular motions. water (and gull) return to original position. the wave form moves forward. Motion decreases with depth. At. a depth of ½ of the wavelength, the motion is not significant.. Introduction. Solar flares occur when energy is converted into x-rays ,heat & supersonic fluid motion.. Energy is stored in magnetic filed lines.. Electric field changes connectivity of magnetic field lines and the energy is released..
