The paper considers the fate of the electrically charged (Ze ≈ 10e) Planckian elementary black holes, namely, daemons, making up the dark matter of the Galactic disc, which, as follows from our measurements, were trapped by the Earth during 4.5 Gyears in an amount equal to approximately 1024. Owing to their huge mass (about 2 × 10−8 kg), these particles settle down to the Earth's centre to form a kernel. Assuming that the excess flux of 10-20 TW over the heat flux level produced by known sources, which is quoted by many researchers, is due to the energy liberated in the outer kernel layers in daemon-stimulated proton decay of Fe nuclei, we have come to the conclusion that the Earth's kernel is at present a fraction of a metre in size. The observed mantle flux of 3He (and the limiting 3He to 4He ratio of about 10−4 itself) can be provided if at least one 3He (or 3T) nucleus is emitted in a daemon-stimulated decay of 102-103 Fe nuclei. This could actually remove the only objection to the hot origin of the Earth and to its original melting. The high energy liberation at the centre of the Earth drives two-phase two-dimensional convection in its inner core (IC), with rolls oriented along the rotation axis. This provides an explanation for the numerous features in the IC structure revealed in recent years (anisotropy in the seismic wave propagation, the existence of small irregularities, the strong damping of the P and S waves, ambiguities in the measurements of the IC rotation rate, etc.). The energy release in the kernel grows continuously as the number of daemons in it increases. Therefore the global tectonic activity, which had died out after the initial differentiation and cooling off of the Earth was reanimated 2 Gyears ago by the rearrangement and enhancement of convection in the mantle as a result of the increasing outward energy flow. It is pointed out that, as the kernel continues to grow, the tectonic activity will become intensified rather than die out, as was believed before.
