WebNov 10, 2004 · The heat, which is vibrations of atoms in the solid pan, moves as a result of fast moving (hot) atoms bouncing off slow moving (cool) atoms, causing the slow atoms to move faster (heat up). So at the top of the asthenosphere, the hot rock flows along the bottom of the lithosphere, transferring its heat to the cold rocks by conduction.
