 Geosphere

The crust of Earth consists of a shell called the geosphere. The Geosphere is that component of the Earth system where mineral wealth in the form of metals, coal and oil are found. Surface topography, combined with the movement of water across the landscape and distribution of fertile soils, is the dominant factor determining where we grow our crops. This sphere includes all the stuff that makes up the crust and the core of the earth. It includes everything natural and lifeless that makes up the surface of the earth. In modern text in Earth system science, geosphere refers to the solid parts of the Earth; it is used along with atmosphere, hydrosphere, and biosphere to describe the systems of the Earth. Sometimes the term lithosphere is used instead of geosphere or solid Earth. The lithosphere, however, only refers to the uppermost layers of the solid Earth. The geosphere undergoes infinite processes constantly and that, in turn, modifies other spheres. One example of the continuous process is the rock cycle; it is influenced by other factors such as water, temperature, and wind, which also belong to other spheres
