GeophysicsThe geophysics is a scientific discipline focused on the study of terrestrial physics. This branch of the geology is responsible for analyzing the Earth from the perspective of physics, taking into account the history of the planet, its structure and other factors.

For the development of its studies, geophysics resorts to various quantitative methods, measuring the electromagnetic fields, the radiation and the gravity, for instance. Depending on the specific field of study, one can differentiate between external geophysics, which focuses on the environment of the planet, and the internal geophysics, specialized in the terrestrial interior.

The meteorology, the climatology, the gravimetry and the space geophysics are some of the specializations linked to external geophysics. The seismology, the volcanology and the geodynamicsInstead, they are associated with internal geophysics.

Let’s see below some details of the disciplines just mentioned. The meteorology is responsible for studying the atmosphere and the so-called atmospheric weather, taking into account the scope of the troposphere (the layer of the Earth’s atmosphere that reaches its surface). The climatology It can be considered both a branch of geography and a science in itself, and focuses on the climate and the changes it goes through with the passage of chronological time; precisely, the current climate and the past enter its points of interest.

It is known as gravimetry to the branch of physics that is dedicated to the study of gravitation of the Earth and to the measurement of its alterations in the diverse points of the planet. For its development, gravimetry requires observations on the planet itself as well as from some satellites.

With respect to space geophysics We can say that it focuses on the study of the physical processes that are related to the plasma found in the magnetosphere and ionosphere, as well as the way in which they interact with the solar wind. It is especially recognized for its theory linked to the transfer of energy that originates the auroras polar.

GeophysicsThe seismology focuses on the internal structure of our planet, on telluric movements and on that of the tectonic plates, among other topics. To do this, it takes advantage of seismograms, which provide readings of seismic waves. The study of phenomena related to volcanoes, magma and lava is known as volcanology, a discipline that has also led scientists to discover low-temperature volcanic activity in bodies such as Enceladus, the sixth largest satellite of Saturn.

The geodynamics It is the part of geology that specializes in the forces and agents that participate in the dynamic processes of our planet. Like geophysics, it is divided into a field that studies the phenomena internal and another that focuses on external.

What geophysics does is help to understand how our planet worked and how it works from the interpretation of physical processes. In this way, a geophysicist can explain how hurricanes form or why the earth shakes. Earth, for instance. Their knowledge not only contributes to the understanding and measurement of phenomena: they are also useful for predicting certain natural events.

It is important to note that geophysics is applied in many industries and fields. His studies are used to evaluate the minerals found in the earth’s crust and to analyze their possible exploitation. On the other hand, they can indicate which are the appropriate lands for the development of a work of engineering or how a drilling for hydrocarbons should be carried out.
