EVOLUTION OF GEOPHYSICS

Abstract

Geophysics is the study of the physics of the Earth and its environment in space. One emphasis is the exploration of the earth's interior using physical properties measured at or above the earth's surface together with mathematical models, to predict those, properties. Sub-disciplines includes, seismology, the study of seismic waves; geomagnetism. The study of the magnetic field, and geodesy the study of the gravitational field and the shape of the Earth's surface.

Seismology– provides key evidence for large-scale earth structure and for the behaviour of earthquakes. Mineralogy, and hence density and other physical properties at depth, is deduced from experiments and mathematical modeling in mineral-physics. Mathematical models underpinning geophysics also predict the large-scale movements within the earth. Geophysics is reliability a new discipline in comparison to geology, contrary to general perception as an ancillary to geology, the discipline has been developed with a distinct. Focus of using the principles and methods of physics for the earth processes.

Geophysics was born in the nineteenth century as a necessary element of theoretical geography. Academicians and researchers in the field of geography played chief roles from its birth to its present level of maturity.

Historical scholarship in the paper provides an account of the development of the discipline over hundred years from its inception in the early nineteenth century. The article covers, how the discipline was conceptualied and what necessary steps were taken, such as establishing learned Scietus Publishing technical journals and text books, endowing university chaire, opening up departments and course curriculum and most importantly, appearing as a primary discipline to carter to exploration for mineral resources.
