WebDirectly below the lithosphere is a less fixed, warmer region of the upper mantle called the asthenosphere. Here, the temperatures are so high that, in places, the rock that makes up the asthenosphere melts into liquid. Only tiny parts of the asthenosphere are liquid, but it is soft enough to move, pushing around the plates above.
