It is called geosphere to the solid sector of our planet which is formed by concentric layers . It's about the internal structure that goes from the earth's core to the lithosphere.
The Royal Spanish Academy (RAE ) accept both the term geosphere (emphasized in the second AND ) as geosphere (with tilde on the OR ). Therefore it can be a serious word or esdrújula, according to the chosen form.
The geosphere forms the Ocean floors , thus counting on submerged parts. It also emerges in the development of islands and the continents . In the broadest sense, three concentric layers are recognized: nucleus , he mantle and the Cortex .
The innermost layer is the nucleus , which is at a very high temperature. The core can be divided into internal core and external core, which are integrated by metals Like iron The intermediate layer is called the mantle, where magma is found. Finally, the outermost layer is the cortex. The upper part of the mantle and the crust, on the other hand, form the lithosphere (or lithosphere).
The minerals that form the rocks They are the crust component, the surface layer of the geosphere. These minerals determine the properties of rocks, such as their hardness, brightness or color. According to their origin, rocks can be metamorphic (arising from compression or heating of other rocks), igneous (created by solidification of magma) or sedimentary (which appear by the union of parts of rocks or remains of living beings).
