This book includes the fundamental geophysical knowledge acquired to date on the topics of the structure, composition, and physical changes of the Earth's interior.

In nine chapters and more than 260 figures, it elaborates on the relationship of the Earth with the solar system, the structure of the Earth's interior, basic geodynamics (the theory of lithospheric plates, etc.), the production and propagation of heat within the Earth, natural radioactivity, and radiocarbon dating methods, the Earth's gravitational and magnetic field, as well as the basic seismic methods for studying the structure of the Earth's interior.

Additionally, in the last chapter, various topics on the application of specific geophysical techniques and methods are discussed. Each chapter includes basic and advanced level exercises, and at the end of the book, detailed information and figures for solving the exercises are provided.

It is aimed at readers with a geological scientific background (students, scientists, and professional geologists, geotechnicians, etc.), as well as other natural scientists (mathematicians, physicists, engineers, etc.) who are interested in geophysical topics.
