Geophysics is the study of the Earth's physics and structure using mathematical and physical methods. This includes everything from an understanding of the microscopic properties of minerals and rocks, to an understanding of global processes such as earthquakes and climate.
Geophysics is a subject of natural science concerned with the physical processes and physical properties of the Earth and its surrounding space environment, and the use of quantitative methods for their analysis. The term geophysics sometimes refers only to solid earth applications: Earth's shape.its gravitational and magnetic fields its internal structure and composition; its dynamics and their surface expression in plate tectonics the generation of magmas, volcanism and rock formation. However, modern geophysics organizations and pure scientists use a broader definition that includes the water cycle including snow and ice; fluid dynamics of the oceans and the atmosphere; electricity and magnetism in the ionosphere and magnetosphere and solar-terrestrial physics and analogous problems associated with the Moon and other planets.
