Geosphere definition

1 answer

The term "geosphere" refers to the solid part of the Earth, encompassing all the rocks, minerals, and landforms, as well as the interior layers of the Earth, including the crust, mantle, and core. It is one of the four main spheres of Earth systems, alongside the hydrosphere (water), atmosphere (air), and biosphere (life). The geosphere includes terrestrial features such as mountains, valleys, and soil, as well as geological processes like erosion, sedimentation, and plate tectonics that shape the Earth's surface.
