The asthenosphere.
The continents are embedded in the top side of crustal plates which float on the surface of the mantle. Convection currents in the mantle carry the plates around and the embedded continents travel along.
mantle.
convection currents in the mantle provide the basic driving forces for plate motions.
The entire crust (or outer layer) of the planet Earth is composed of plates, and the movements of those plates are described by the science of plate tectonics.
They'd stop moving.
The worlds tectonic plates slide on the earths mantle.
Lower mantle is the surface on which the lithospheric plates move around earths surface.
The plates move
plates actually float on earth's mantle

Moving plates in the earths mantle.
The asthenosphere.
Tectonic Plates float on top of the earths mantle, the earths mantle is made up liquid which is always circulating.
They move because the plates in Earths mantle shift and cause the island to move slightly. As the plates move around they cause changes in Earths landforms. The more pressure is on the plates the more they move around. Because of Japans tsunami and earthquakes, the plates were moved around to Hawaii and possibly could have caused an island to move. If you wander what plates are well they are rigid blocks of crust and upper mantle rock.
