Ultra low velocity zones are found above this layer. This layer is the outermost of the two layers separated by the Lehmann discontinuity, and the innermost of the two layers separated by the Gutenberg discontinuity.
Ultra low velocity zones are found above this layer. This layer is the outermost of the two layers separated by the Lehmann discontinuity, and the innermost of the two layers separated by the Gutenberg discontinuity. Shadow zones are created due to the fact that (*) S waves are completely stopped by this layer and P waves are refracted by it. Geodynamo theory posits that earth's magnetic field is generated by the rotation of nickel and iron in this liquid layer. For 10 points, name this layer of the earth located between the mantle and the inner core.
