This guide focuses on essential geophysical equations, providing students with clear derivations to aid in understanding complex concepts. It serves as a practical resource for tackling homework and preparing for exams, emphasizing clarity and accessibility in the presentation of material.
Geophysics is the physics of the Earth. It encompasses seismology, volcanism, plate tectonics, gravitational anomalies, and changes in the Earth's magnetic field (present and past). William Lowrie describes how all these give clues to the structure and working of the planet.
The book describes and explains the Earth's magnetic field, its historical importance, and various ways in which geomagnetism is used, including the analysis of modern satellite-based investigations.
