The study of Geology is somewhat specialized but also very rewarding and has been around since the 1930 s, progressing everyday with new and innovative methods and even computer software. In order to be successful in geological studies the correct use of the geophysical instrument is required; there are various instruments available, each with a specific usage. Geophysics includes the study of archaeology and that of earthquakes and common instruments used are land and water magnetometers, seismographs and geoelectrical instruments. Seismographs are used in ground water studies as well as studies of surface wave and reflection. Geophysics may seem somewhat complex to the absolute beginner but this fascinating study of the earth, its soil, rock, and movements is a fascinating insight to the formation of our planet. Once you have learned the basics, you will find that there are subdivisions within this science such as mineralogy, hydrology, geomorphology and geophysics. Through the correct use of appropriate geophysical instrumentation such as seismographs and magnetometers the formation of the earth s crust can be studied. The instruments also allow for the individual to monitor the intensity and duration of an earthquake as well as finding its source. Magnetometers on the other hand are used more in the field of archaeology and through the discovery of magnetic fields, many wrecks of ships and other fascinating metal objects have been unearthed. The detection of oil has also been made possible through the use of such instrumentation, making this science not only fascinating but also productive. When you wish to study geophysics it is essential that you acquire the correct training; self taught geophysicians are hard to come by. In the twenty first century this science has also been combined with computer technology and software that has allowed an even deeper understanding of our earth s formation.
