The tectonic plates (the lithosphere) are made of the crust and upper brittle part of the mantle. They 'float' on the hotter and softer mantle below, which is still a solid, but can flow like plasticine (the asthenosphere)

What are the tectonic plates float on?

Tectonic plates float on the asthenosphere, which is a semi-fluid layer of the Earth's mantle. This allows the plates to move and interact with each other, causing geological phenomena such as earthquakes and volcanic activity.

Is asthenosphere a plate boundary?

No. The asthenosphere is a ductile layer of the mantle that tectonic plates float on top of.
