I think it's called a plate
The layer of the Earth that contains both the crust and upper mantle is called the Lithosphere.
The lithosphere is the crust Moho and upper mantle. It floats on a plasticity zone called the asthenosphere.
Lithosphere
It is called the lithosphere.
Earth's crust and brittle upper mantle is called the lithosphere.
Crust and the upper mantle
upper mantle
The crust and uppermost hard rocky mantle, together, is known as the lithosphere, which is above the plastic-like upper mantle area known as the asthenosphere.
The crust and upper mantle make up the earth.
The upper level of the mantle is called the asthenosphere. It is a semi-fluid layer of the Earth's mantle located just below the lithosphere. The asthenosphere plays a key role in the movement of tectonic plates.
The upper rocky layer of Earth is called the lithosphere. It includes the Earth's crust and the uppermost part of the mantle.
Between the thin rocky crust and inner core, in order from upper to lower, are the upper mantle, mantle, and outer core.
