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
No the tectonic plates are on top of the crust.
Tectonic plates are segments of the lithosphere. They float on top of the asthenosphere.
The crustal plates (both continental and oceanic) float on the denser mantle.
plates of the earth's crust that float on top of the molted mantle layer.
Tectonic plates move because they are floating on top of the liquid mantle.
How do I find out how much my plates are worth?
