The paper considers the fate of the electrically charged (Ze~10e) Planckian elementary black holes - daemons - making up the dark matter (DM) of the Galactic disk, which, as follows from our measurements, were trapped by the Earth during 4.5 Gyr in an amount of ~10^24. Due to their huge mass (~2x10^(-8)kg), these particles settle down to the Earth's center to form a kernel. Assuming the excess flux of 10-20 TW over the heat flux level produced by known sources, which is quoted by many researchers, to be due to the energy liberated in the outer kernel layers in daemon-stimulated proton decay of iron nuclei, we have come to the conclusion that the Earth's kernel is presently measured in few fractions of meter in size. The observed mantle flux of 3He (and the limiting 3He/4He ~ 10^(-4) ratio itself) can be provided if at least one 3He(or 3T) nucleus is emitted in a daemon-stimulated decay of ~100-1000 Fe nuclei. This could remove actually the only objection to the hot origin of the Earth and to its original melting. The high energy liberation at the center 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 the recent years. 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 Gyr 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 this was believed before.
