The Earth's tectonic plates are in constant motion. This movement is possible because they lay on top of the asthenosphere which is the outer mantle.
the plates float on top of the upper mantle
The tectonic plates float on the lithosphere. This overlies the asthenosphere.
There called tectonic plates, and they do not float on anything.

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.
They don't. Tectonic plates float on the asthenosphere, as they are a bit less dense.
