| Abstract: | The key trends and problems in the study of interactions between the geospheres in the near-surface areas of the continental
crust of the Earth which are of most interest for the formation of living environment are formulated. The main periodicities
in the variations of geophysical fields determining the natural environmental rhythms are determined. The interactions and
transformations of geophysical fields (electric field in the ground and in the atmosphere, radon emanation field, and the
field of microseismic vibrations) are considered. It is noted that the tectonic discontinuities and weak disturbances in the
solid Earth such as lunar-solar tides and variations in the atmospheric pressure play an important role in the formation of
the regimes of geophysical fields at the boundary of the Earth’s crust and the atmosphere. The synchronous instrumental observations
reveal a mutual influence and significant correlation between the amplitude variations of geophysical fields of different
nature. |
