Geophysics, a major discipline of Earth sciences, is the study of the Earth by quantitative physical methods, especially by seismic, electromagnetic, and radioactivity methods. Earth science (also known as geoscience, the geosciences or the Earth Sciences) is an all-embracing term for the Sciences related to the planet EARTH was a short-lived Japanese vocal trio which released 6 singles and 1 album between 2000 and 2001 Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Reflection seismology (or seismic reflection) is a method of Exploration geophysics that uses the principles of Seismology to estimate the properties of Electromagnetism is the Physics of the Electromagnetic field: a field which exerts a Force on particles that possess the property of Radioactive decay is the process in which an unstable Atomic nucleus loses energy by emitting ionizing particles and Radiation. It calls heavily upon other fields of science such as math, physics, and computer science. History of geophysics has been motivated by theoretical and practical isues. The historical development of Geophysics has been motivated by two factors 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 [1] [2] as "geophysik" in 1834. The theories and techniques of geophysics are employed extensively in the planetary sciences in general. Planetary science, also known as planetology and closely related to planetary astronomy, is the Science of Planets or Planetary systems

The field of geophysics includes the branches of:

  • Atmospheric electricity and terrestrial magnetism (including ionosphere, Van Allen belts, telluric currents, Radiant energy, etc. Seismology (from Greek grc σεισμός seismos, "earthquake" and grc -λογία -logia) is the scientific study of Earthquakes An earthquake is the result of a sudden release of energy in the Earth 's crust that creates Seismic waves Earthquakes are recorded with a Seismometer A wave is a disturbance that propagates through Space and Time, usually with transference of Energy. Earth's gravity, denoted by g, refers to the Gravitational attraction that the Earth exerts on objects on or near its surface Geodesy (dʒiːˈɒdɪsi also called geodetics, a branch of Earth sciences, is the scientific discipline that deals Atmospheric sciences is an umbrella term for the study of the atmosphere, its processes the effects other systems have on the atmosphere and the effects of the atmosphere Atmospheric electricity is the regular diurnal variations of the Earth 's atmospheric electromagnetic network (or more broadly any Earth 's magnetic field (and the surface magnetic field) is approximately a Magnetic dipole, with one pole near the North pole (see The ionosphere is the uppermost part of the atmosphere, distinguished because it is Ionized by solar radiation The Van Allen radiation belt is a Torus of energetic Charged particles ( plasma) around Earth, held in place by Earth's Magnetic A telluric current (from Latin tellūs, "earth" is an Electric current which moves underground or through the sea Radiant energy is the Energy of Electromagnetic waves The quantity of radiant energy may be calculated by integrating Radiant flux (or power )
  • Meteorology and Climatology, which both involve studies of the weather. Meteorology (from Greek grc μετέωρος metéōros, "high in the sky" and grc -λογία -logia) is the Interdisciplinary Climatology (from Greek grc κλίμα klima, "region zone" and grc -λογία -logia) is the study of Climate, scientifically
  • Aeronomy, the study of the physical structure and chemistry of the atmosphere. Atmospheric physics is the application of Physics to the study of the atmosphere.
