Geophysics S-waves in the outer core. This indicates that the outer core is liquid, because liquids cannot support shear. The outer core is liquid, and the motion of this highly conductive fluid generates the Earth's field. The inner core, however, is solid because of the enormous pressure. Reconstruction of seismic reflections in the deep interior indicate some major discontinuities in seismic velocities that demarcate the major zones of the Earth: inner core, outer core, mantle, lithosphere and crust. The mantle itself is divided into the upper mantle, transition zone, lower mantle and "D′′" layer. Between the crust and the mantle is
The Core as those found in "The Core". In a poll of hundreds of scientists about bad science fiction films, "The Core" was voted the worst. On February 21, 2010, "The Guardian" ran an article about American professor Sidney Perkowitz's proposals to curb bad science in science fiction movies. In the article, Perkowitz is said to have hated "The Core". "If you violate [the coherent rules of science] you are in trouble. The chances are that the public will pick it up and that is what matters to Hollywood. "The Core" did not make money because people understood the science was so
