We explain what the geosphere is and how its structure is. In addition, how this sets of layers is composed and its importance.
In the natural sciences , the set of layers that constitute the solid part of the Earth is called a geosphere or geosphere . Together with the hydrosphere (aquatic part), the atmosphere (gaseous part) and the biosphere (set of living beings ), they form the parts into which our planet can be analytically divided.
Like other terrestrial (solid surface) planets, the Earth is formed of rocky materials of different nature and that have different dynamics from each other, many of which date from the first geological periods or were formed during convulsive stages of volcanic activity. Many of the oldest known rocks on the planet date back more than 4400 million years ago.
The study of the geosphere by geologists and other specialists, is carried out by experimental review of the soils , especially in places where land accidents reveal strata that would normally remain hidden.
In the same way, many observations are theoretical or derived from the calculation: the mass and volume of the earth are not directly measurable, but through other calculable variables, such as gravity , or the reverberation of seismic waves.
The structure of the geosphere is studied from two different perspectives: from the chemical point of view and from the geological point of view.
Taking into account the point of view of its chemical composition, the geosphere comprises three layers: crust, mantle and core.
Instead, from a geological point of view, the geosphere is divided into:
The geosphere is the oldest portion of our planet and where all its secrets are enclosed . Geology scholars try to discover the various processes involved in their formation, which also shed light on the formation of the rest of the solar system’s stars and, therefore, the origin of the universe. The same goes for seismology, a science that tries to understand the nature of geological and tectonic movements to prevent eventual earthquakes and prevent them from being so destructive to humanity.
On the other hand, the study of the geosphere goes hand in hand with the understanding of the materials that we can find on our planet, which has important repercussions in the various industries, engineering and international trade, among other vital areas.
