Geophysics explores how physical principles can be applied to study processes operating in, on and around our planet, such as motion within its core tectonic movements, dynamics of the oceans and atmosphere, and the interactions in space between the solar wind and the Earth’s magnetic field. At a practical level, engineers employ geophysical methods to explore below the Earth’s surface in the search for oil, gas and other natural resources as well as for scientific investigation. Increasingly, geophysicists are involved in monitoring the environment and assessing natural hazards, whether global or connected with specific engineering projects.
