This hypothesis...
shear energies/ A9135 Earth interiorSOLIDITY of the inner core was originally inferred on the basis of the assumption that the inner core has the same composition as the surrounding material of the outer core 1 . If, however, the observed increase in compressional velocity is related to a ...
