Lithosphere is the crust and uppermost mantle make up a rigid outer layer.

Beneath the lithosphere, the rocks become partially molten, or melted. They are able to slowly flow because of the uneven distribution of heat deep within Earth. This region is called the asthenosphere. Beneath the asthenosphere, the rock becomes more dense. This region of Earth is called the lower mantle.

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the uppermost part of the mantle. It is divided into several large and small tectonic plates that float on the semi-fluid asthenosphere below.
