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
The rigid layer of the uppermost mantle and crust is known as the lithosphere. It consists of the Earth's crust and the uppermost part of the mantle, forming a solid outer shell that is rigid and brittle. The lithosphere varies in thickness and is divided into tectonic plates that float on the underlying semi-fluid asthenosphere. This layer plays a crucial role in geological processes such as plate tectonics and earthquakes.
it is the crust because the crust is thin and rigid with rock

The Inner Core is a liquid. Outer core: solid mantel: inbetween crust: solid
lithosphere
Earthâ??s mantle is the layer underneath the crust. It is composed of silicates and is nearly 2 thousand miles thick.
the Lithosphere or Lithospheric Plates
It is a fault.
It's called the lithosphere.
