There is no specific term for such a general block. "Lithospheric block" would be acceptable, but it would be best to describe exactly what you mean by it.

the Lithosphere or Lithospheric Plates
it is the crust because the crust is thin and rigid with rock
A large rigid section of the Earth's crust is known as a tectonic plate. These plates float and move on the semi-fluid asthenosphere beneath them, and their interactions at plate boundaries often result in geological phenomena like earthquakes and mountain formation.

The Inner Core is a liquid. Outer core: solid mantel: inbetween crust: solid

the Lithosphere or Lithospheric Plates
Earthâ??s mantle is the layer underneath the crust. It is composed of silicates and is nearly 2 thousand miles thick.
It is a fault.
It's called the lithosphere.
