• The lithosphere is mostly liquid, with some medium-density materials, such as silicon.

• The lithosphere is more plastic and flows slowly compared to the solid crust of Earth.

• The lithosphere includes the core and the lower portion of the mantle.

What is the layer of the earth that is solid but behaves somewhat “plastic”,

malleable and deform with pressure

• Crust

• Upper Mantle

• Lower Mantle

• Inner Core

How do scientist discovered the earth's interior?
