Geophysics, a major discipline of the Earth sciences, is the study of the Earth by the quantitative observation of its physical properties, especially by seismic, electromagnetic, radioactivity, galvanic (electrical) and potential field (such as gravity and magnetism) methods. Geophysics can therefore be seen as the intersection of geology and physics. It calls heavily upon other fields of science such as mathematics and computer science. The theories and techniques of geophysics are employed extensively in the planetary sciences in general.
ds which are part of or related to geophysics include:
History of geophysics The development of geophysics has been motivated by many theoretical and practical issues.
The term of geophysics was probably first used in Germany, where it appeared in scientific writings of the mid-19th century.

Fields and related disciplines
Fields which are part of or related to geophysics include:
- Most of our knowledge of the Structure of the Earth derives from seismology
- Shallow seismology is used in exploration geophysics (to find oil and gas) and for environmental characterization of the subsurface
- Volcanology, the study of volcanoes, together with hot springs and, more widely, heating and heat flow within the Earth
History of geophysics The development of geophysics has been motivated by many theoretical and practical issues.
The term of geophysics was probably first used in Germany, where it appeared in scientific writings of the mid-19th century. The word geophysics was first used by Fröbel as "geophysik" in 1834.
