It is when Earth's tectonic plates move around.
tectonic plates
Magma moving underneath the earth causes tectonic plates to move about.
It is verified by GPS.
The tectonic plates, part of the lithosphere, move around and float on the top of the asthenosphere.
They are called tectonic or lithospheric plates.
Earth's tectonic plates move due to the heat-driven convective flow of mantle material beneath them. This process creates forces that push and pull the plates, causing them to move around the Earth's surface.
If you mean for the plates that are the earth's crust they are called 'Tectonic Plates'.
The upper mantle contains convection currents that move the tectonic plates.
Plate Tectonics is the process by by which the earth's tectonic plates move.
The asthenosphere.
Tectonic plates move because of the heat and pressure from the Earth's core, causing convection currents in the mantle that push the plates apart or pull them together.
