What is the geosphere made of?

The geosphere is the solid, rocky part of the earth's surface. It includes the crust, the inner and outer core, and the mantle, which is the largest layer. The crust is the thin outer layer of the earth, and it's divided into two types: oceanic crust, which is denser and younger, and continental crust, which is less dense and older. The mantle is a dense layer of rock beneath the crust, and it's responsible for the movement of tectonic plates. The outer core is a liquid layer that surrounds the inner core, which is a solid ball of mainly iron and nickel. The geosphere is constantly changing due to volcanic eruptions, earthquakes, and other geological events.
