This book includes the basic knowledge of Geophysics that has been acquired so far on topics of structure, composition, and natural variations of the Earth's interior. In nine chapters and over 260 figures, the relationship between the Earth and the solar system, the structure of the Earth's interior, basic Geodynamics (theory of lithospheric plates, etc.), the production and propagation of heat in the Earth's interior, natural radioactivity and radiometric dating methods, the gravitational and magnetic field of the Earth, as well as the basic seismic methods for studying the structure of the Earth's interior are elaborated in detail. In addition, various topics of application of special geophysical techniques and methods are developed in the last chapter. Each chapter includes exercises of basic and advanced level, and at the end of the book, detailed information and figures are provided for the solution of the exercises.

It is addressed to readers with a geological scientific background (students, scientists, and professional geologists, geotechnical engineers, etc.), as well as to other physical scientists (mathematicians, physicists, engineers, etc.) interested in Geophysics.
