The scientific literature is not elaborate enough
to consider the importance of the seasonal location
of the core of the Earth as a factor of geodynamic
processes [Greiner-Mai et al., 2003; Antonov, Kon-
dratjev, 2004; Malyshkov Yu., Malyshkov S., 2009].
In our work we present a logical rational of the con-
cept.
The first position. Newton's second law of the
force of gravity states that there is a direct propor-
tional relation to the mass of bodies and inversely
proportional to the distance between them. Weight
is calculated as the product of the specific body
weight and its volume. The core of the Earth has a
larger proportion (this fact is proved by numerous
gravimetric studies) [http://uk.wikipedia.org/wiki/
Geophysic].
It is known that the Earth's core consists of 90%
iron while the mantle contains of only 10 % iron
and a proportion of the other elements — oxygen,
silicon and magnesium [Allegre et al., 1995].
Therefore, the force of gravity per unit volume of
Earth's core is higher and the nucleus constantly
presses the inside the mantle. Pressure is directed
towards the Sun and as the Earth rotates the con-
stantly changing area of highest pressure is inside
the kernel.
So, the Earth's core is heavier, and in accor-
dance with Newton's second law, more attracted to
the sun. This is partly accounted for in the scienti-
fic literature.
The second position. The axis of the Earth is
tilted 23 degrees to the ecliptic plane. Earth is fa-
cing the Sun at an angle, in the summer inside the
nucleus at an angle of more pressure on the nor-
thern hemisphere, and in the winter — on the Sou-
thern.
Findings from the provisions of 1 and 2.
The core of the Earth not only rotates inside the
planet, but also seasonally shifts to the Northern
Hemisphere and then to the Southern, as shown in
the picture (Figure).
In the presented picture (when the Earth is right)
shows how the Earth's core is offset at an angle of
23 degrees in the direction of the Northern Hemi-
sphere, when we have the summer season.
Inside — the pressure on the mantle. The pic-
ture also shows (when the Earth is on the left) as
the core is offset at an angle to the Southern Hemi-
sphere, when we have the winter season.
Such internal displacement of the Earth's core
(as conventionally shown "on the cut") reaches its
highest value in the following periods: December—
January and June—July.
The pressure inside the kernel, its friction and
seasonal shifts significantly affects:
earthquakes and volcanoes,
the movement of continents and the forma-
tion of mountain ranges,
the formation of plumes, subduction, nuta-
tion, and other geodynamic processes.
During the summer, forming elevations in the
Northern Hemisphere, are active volcanoes, earth-
quakes that occur in the projections of the nucleus
and the more pressure field "breaks" of tectonic

plates. Seasonal shift in the Earth's core could ex-
plain the gaps of tectonic plates and their move-
ment.
During our winter season, shaped elevations in the
Southern Hemisphere are active volcanoes, earth-
quakes occur in the relatively "weak" field. In the nor-
thern hemisphere, meanwhile, it may also occur from
an earthquake, but the land, that "sinks", hence an
understanding for the reasons for subduction.
Seasonal location of the core of the Earth is im-
portant geodynamic effects, as evidenced by the
presence of zones of high tectonic activnosi on both
sides of the equator. This increases the tectonic
activity in the Southern Hemisphere in December—
January, and in the Northern — in June and July.
The core of the Earth — it is almost a "perpetual
motion" inside the planet until there is a structure
of the Earth's axis and the trajectory of the Earth
around the Sun.
This concept should be considered when crea-
ting a computer model of the Earth, a view of the
seasonal movement of the nucleus, in order to bet-
ter predict those processes that will occur inside
and on the surface of our planet.
