Magma.
The three layers of the lithosphere are the crust, the uppermost part which is divided into the continental and oceanic crust; the mantle, a semi-solid layer beneath the crust; and the rigid lithospheric plates that float on the semi-fluid asthenosphere below.
They don't. Tectonic plates float on the asthenosphere, as they are a bit less dense.
When tectonic plates move, continental plates tend to float higher on the asthenosphere compared to oceanic plates. This is because continental plates are generally thicker and less dense, composed mainly of lighter granitic rocks, whereas oceanic plates are thinner and denser, primarily made of basalt. The lower density of continental plates allows them to "float" more buoyantly on the semi-fluid asthenosphere beneath.
Asthenosphere
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.

There called tectonic plates, and they do not float on anything.
The tectonic plates float on the lithosphere. This overlies the asthenosphere.

The lithosphere is the rigid outer part of the Earth consisting of the crust and upper mantle. It is divided into tectonic plates that float on the semi-fluid asthenosphere below. The lithosphere is involved in processes such as plate tectonics and is where most landforms and mountain ranges are located.

Tectonic plates float on the mantle because they are less dense
The tectonic plates, part of the lithosphere, move around and float on the top of the asthenosphere.
Tectonic plates float on an underlying molten layer.
The crustal plates (both continental and oceanic) float on the denser mantle.
