What is the Meaning & Definition of Geosphere

It is called under the term of Geosphere to different material layers of planet Earth that are placed between the atmosphere and the planetary core. This set of geological layers contains very diverse elements together in terms of characteristics and conditions such as temperature, matter, density, energy, etc.
The geosphere of our planet can be divided into five main parts. Views from the outside toward the inside of the planet, we can say that the atmosphere is the first, composed of different gases and located above the surface. The atmosphere is that connects the Earth's surface to outer space. Then the surface or crust that is best known for the human being, that is located (and only) which can live and develop their activities permanent and natural. The Earth's crust or surface varies in its characteristics in the different spaces both with respect to the material that composed it, its density, its temperature and humidity, etc.
The following geological layers of the Earth are the underground layers to which the human being has no access in terms of permanent or natural habitat. They are the mantle (located from 40 to 70 km below the crust), (2,900 km) outside core and the inner (to 5.140 km) core. The latter represents the smaller share of material between the different geological layers and possesses the highest temperature recorded on the planet: around 6000 degrees Celsius.
In the different layers of the geosphere is the matter in different ways. While some found in solid form (as the case with the rocks of the Earth's crust or the inner core, which is kept in the solid state as a result of the strong pressure exerted on him by the rest of the layers), in others appears in form gaseous (such is the case of the atmosphere) and other liquid (such as liquid or magma that exists in the mantle or the outer core).
