The layer of the earth that allows the tectonic plates to move around above it is the mantle. The mantle is also known as the hot molten magma layer called the asthenosphere.
The tectonic plates are composed of the lithosphere (which is the Earth's crust and the brittle solid portion of the upper mantle).
They move on top of the mantle, the 'asthenosphere'.
The Lithosphere which is formed from the rocky outer part of the the upper mantle and the crust.

the crust
The structure of the Earth relates to plate tectonics as in the Earth structure there is the mantle layer, crust layer, inner and outer layer etc. The crust layer on top of the Earth is not a solid layer, the layer the broke up into big chunks which are now called tectonic plates.
The crust. These plates of the earth's surface/crust slowly move over the magma in the earth because of convection and other forces. The theory of these plates moving is known as 'plate tectonics'.
Plate tectonics... I wish you would be more specific.
The plates are part of the crust, the upper layer of the Earth. The plates are moved by currents in the upper mantle. The plates and flexible upper mantle are referred to collectively as the lithosphere and sit atop the mantle layer called the aesthenosphere.
The crust, the layer we live on.
The Lithosphere is a mechanical layer on Earth that contains seven major plates.

the crust
These plates make up the top layer of the Earth called the lithosphere. Directly under that layer is the asthenosphere. It's a flowing area of molten rock.
