Asthenosphere
no
The movement of crustal plates is driven by heating from within the mantle, as the separate plates sit atop the fluid asthenosphere. The difference in rock motion means that plates can be pushed into, over, and under each other.

how much are top plates
The asthenosphere.
cocos plate
tectonic plates
The Earth's tectonic plates do not move on top of the crust, they are the crust. The crust is made out of plates. The plates float on top of the mantle, which is made of molten rock, called magma. The plates move because of currents in the magma.

The answer is Tectonic Plates
the plates float on top of the upper mantle
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)
No the tectonic plates are on top of the crust.
