The asthenosphere.
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.
The earth's tectonic plates are said to "float" on layers of magma, which is molten, or very hot liquid rock deep under the surface of theearth.
It is the theory of plate tectonics.
Tectonics is the theory that the earth's surface is split into plates that float on the surface of semi-molten rock known as the mantle layer. For instance, as the plates are on the move, (albeit, extremely slowly) the India Plate colliding (converging) with the Asian Plate resulted in the formation (upthrust) of the Himalayas.

plates of the earth's crust that float on top of the molted mantle layer.
The outer layer of the earth where the land masses are is called the crust
