 
 <prompt> Geophysics na one subject for natural science wey dey look the physical processes and properties of the Earth and the space wey dey around am, and how dem dey use quantitative methods to analyze am. Dem dey refer to geophysical applications like Earth shape, gravitational and magnetic fields, internal structure, dynamics, plate tectonics, magmas, volcanism and rock formation. Geophysics organizations dey use broad definition wey include water cycle, fluid dynamics of oceans and atmosphere, electricity and magnetism for ionosphere and magnetosphere, solar-terrestrial relations, Moon and other planets. Geophysics start from ancient times but e be recognized as separate discipline for 19th century. Magnetic compasses and seismic instruments don dey since ancient times. Isaac Newton apply him mechanics theory to tides and equinox precession. Instruments dey develop to measure Earth shape, density, gravity field and water cycle components. For 20th century, geophysical methods dey develop for remote exploration of solid Earth and ocean, and e play important role for plate tectonics theory development.
