Lithosphere=

Which layer is described as:

-appears to have characteristics of a liquid.

-is about 1,400 miles thick.

Which layer of the mantle is described as:

-solid but can flow like a liquid due to the tremendous heat and pressure.

-responsible for convection currents, which may be the driving force for the movement of lithosphere plates

Atmosphere =

Which layer is described as:
