The crust is the Earth's only solid layer. – mantle & inner core are solid
The inner core of the Earth is solid and made primarily of iron.
Temperature and pressure increase toward the center of the Earth.
The asthenosphere is the thinnest layer. –lithosphere or crust
Tectonic plates are pieces of the asthenosphere. - lithosphere
All tectonic plates have continental crust.
