Geophysics is a subject of natural science related to the physical processes and physical properties of the Earth and its surrounding spatial environment, and the use of quantitative methods for its analysis. The term geophysics sometimes refers only to geological applications: shape of the Earth; its gravitational and magnetic fields; its internal structure and composition; its dynamics and its superficial expression in tectonic plates, the generation of magmas, volcanism and rock formation. However, modern geophysical organizations 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 relationships; and analogous problems associated with the Moon and other planets.
Although geophysics was only recognized as a separate discipline in the nineteenth century, its origins go back to antiquity. The first magnetic compasses were made of lodestones, while the most modern magnetic compasses played an important role in the history of navigation. The first seismic instrument was built in 132 AD. Isaac Newton applied his theory of mechanics to tides and the precession of the equinox; and instruments were developed to measure the shape of the Earth, the density and the gravity field, as well as the components of the water cycle. In the 20th century, geophysical methods were developed for remote exploration of solid Earth and ocean, and geophysics played an essential role in the development of the theory of plate tectonics.
