Within the many sub-disciplines of Earth sciences, geophysics is far more significant than other fields. Geophysics involves the study of Earth by means of quantitative and physical means. Particular such quantitative physical methods pertain to electromagnetic, seismic, as well as radioactivity methods. Geophysics utilizes the fundamentals and principals of many other science fields such as computer science, mathematics and physics. The focal points of research in geophysics are mainly upon practical and theoretical issues. Geophysics was considered as a separate field of Earth sciences in the mid nineteenth century and was a common term published in scientific journals of this century. The techniques and theories of geophysics are vastly applied in the overall planetary sciences.

Both geophysics term and research papers are written in APA and also CSE/CBE Styles. Although, other writing styles may also be used depending upon institutional requirements as well as on level of the papers. Within the discipline of geophysics there are many sub-disciplines such as seismology pertaining to elastic waves and earth quakes. A geophysicist studies the Earth by employing electrical, magnetic, gravitational and also seismic methods.  Most geophysicists spend their time working on computer models for calculations for finding copper, iron, oil or any other minerals. Whereas, other geophysicists spend their time analyzing and observing different physical features of the Earth. There are other aspects of geophysics, for instance, there is a separate sub-discipline for studying and evaluating environmental hazards and associated natural factors in construction sites or dams.
