Geophysics is a natural science that deals with the study of the physical properties and processes of the Earth and its surrounding environment. It encompasses the study of the Earth's internal structure and composition, shape and dynamics, as well as the processes of rock formation, generation of magma, and volcanism. The study of the phenomena of heat flow, radioactivity, fluid dynamics, electricity and gravity, and their implications on Earth's processes are also under the scope of this field. Geophysical studies are guided by data collected using satellites and space probes, and geodesy. Geophysics is a wide field with applications in exploration of mineral resources, mitigation of natural resources and environmental protection. This book is a compilation of chapters that discuss the most vital concepts and emerging trends in the field of geophysics. It explores all the important aspects of this field in the present day scenario. Researchers and students in this discipline will be assisted by this book.
