What are the names of the layers geosphere?

The geosphere is primarily composed of three main layers: the crust, the mantle, and the core. The crust is the outermost layer, consisting of solid rock and soil. Beneath it lies the mantle, which is composed of semi-solid rock that flows slowly over time. The core, located at the center, is divided into the liquid outer core and the solid inner core, primarily made of iron and nickel.
