BASE GEOPHYSICS

Geothermics is the study of the Earth's heat within its interior. The term " geothermics" derived from two greek words, " Geo " means Earth and " therm " means heat or thermal energy. Hence geothermics simply deals with Earth's heat. Earth's internal heat play an important role which inturn control internal terrestrial processes such as i/ Generation of geomagnetic field ii/ Motion of global lithospheric plates. Sources of Internal Earth's heat . The Earth derived its internal heat from the following major sources 1. Radioactive Decay This is regarded as the main source of Earth  internal heat as a results of disentigration of long lived radioactive isotopes. Heat from this source is regarded to power most of geodynamic processes. Since radioisotopes such as Uranium (U) , Thorium (Th) presents in granite and pegmatites rocks in form of uraninite and uranothorite minerals respectively. 2. Cooling of the Earth This includes the heat remai...

Geophysics is simply the study of the Earth by applying physics principles. Geophysics is the field of geoscience (Earth science) that in one way or another is related with other multidisciplinary natural and planetary science subjects such as environmental science, astronomy, Biology, geography, chemistry. This post will  describe the career path regarding geophysics, as there are interesting things you may want to hear. I hope we will be together until the end of this conversation. Become a Geophysicist Sometimes it gets overwhelming when it comes to know how you can become a geophysicist. To become a profession geophysicist you have to pursue a career in geophysics at least at undergraduate level, Bachelor's degree. You should have atleast higher education undergraduate majors degree in geophysics, geology, geoscience, physics. Also if you have multiple degrees in geophysics and geology is also a good way too, it will reach you where you want to go. This is an entry level qualif...

The first seismographs were built in the late 19th century were a mechanical synthesis of sorts - a seismometer rigged up to transfer its motions to some kind of timekeeping and recording device. Records, which became known as seismograms , were made continuously, by a pen tracing ink lines on paper, or a stylus etching smoked paper, with time "ticks" marked periodically to provide temporal reference points. See figure (3 and 4). What is a Seismograph? Seismograph Is the sensor device used to amplify and detect ground vibrations. Sometimes the word Seismometer is used to infer the same device. Seismographs basically consist of two (2) parts which are, 1. A seismometer: This is a sensor of ground motion 2. A seismic recording system. Basic Working Principle How does a seismograph work? Principle used by the seismometers, is that It works by " Inertia principle" . The most common is by using a mass suspended by a spring. This mass follows the motion of the ground...
