The geosphere is the solid part of the Earth, encompassing all rocks, minerals, and landforms. It extends from the surface down to the Earth's core. The geosphere is constantly shaped by internal processes like plate tectonics and volcanic activity, as well as external forces such as weathering and erosion. It plays a crucial role in supporting life, providing resources, and influencing climate patterns.

The geosphere is divided into several distinct layers. The outermost layer is the crust, which is relatively thin and brittle. Beneath the crust lies the mantle, a much thicker layer composed of molten rock. The deepest part of the geosphere is the core, divided into a solid inner core and a liquid outer core, both primarily made of iron and nickel.

These layers interact dynamically. The movement of tectonic plates within the crust and upper mantle is responsible for earthquakes, mountain formation, and volcanic eruptions. Erosion by wind, water, and ice gradually reshapes the landscape over geological timescales. The minerals and rocks found within the geosphere are essential for human civilization, providing building materials, fuels, and valuable metals. Understanding the geosphere is fundamental to fields like geology, environmental science, and resource management.
