The Earth is composed of several layers, and the solid layers include:
1. **Crust**: This is the outermost layer of the Earth, which is solid and relatively thin compared to the other layers. It consists of continental crust (landmasses) and oceanic crust (the ocean floor).
2. **Mantle**: Below the crust is the mantle, which is primarily solid rock. However, it behaves like a viscous fluid over long periods, allowing for the movement of tectonic plates. The upper part of the mantle is solid and together with the crust forms the lithosphere.
3. **Inner Core**: At the center of the Earth lies the inner core, which is solid due to the immense pressure that exists at that depth. Despite its high temperatures, the inner core remains solid primarily because of this intense pressure.
The outer core, in contrast, is liquid and composed of molten iron and nickel.
