Internal and external forces of the earth
The forces that direct Natural phenomena that have affected geo-material
and still affect it. It is internal for what is happening in depth and external
for what is happening on the surface; the internal phenomena are those which
produce the reliefs; external phenomena are those that destroy them.

Internal
geodynamics
Internal geodynamics, concerns the movements and processes that affect
the interior of the Earth. It is essentially a thermodynamics related to heat
loss caused by the radioactive decay of certain elements. One of the
manifestations more tangible of this dynamic is the displacement of rigid
plates to the surface of the planet, this mechanics is described by the theory
of plate tectonics, which explains great phenomena such as earthquakes,
volcanoes, deformation of the earth's crust and the formation of large mountain
ranges.
External
geodynamics
External
geodynamics studies structure and evolution outer envelopes of the Earth. His
field encompasses all phenomena dissipating energy that comes, more or less
directly, from the radiation Solar, which controls atmospheric and oceanic
circulation, and to have the great characteristics of the oceanic and
continental domains. Thus the external dynamics of the Earth's surface as well
as the products of this dynamic: sedimentary rocks.
