Lithospheric plates.
They are called tectonic (or lithospheric) plates.
Lithospheric plates are large, rigid pieces of Earth's outermost layer, the lithosphere. These plates include both the continental crust and the outermost part of the mantle and float on the semi-fluid asthenosphere beneath them. The movement and interactions of these plates are responsible for many geologic processes, such as earthquakes, volcanic activity, and mountain building.

Yes.

They constantly move. EDIT: Lithospheric plates move only about a few centimeters a year. Hope this helps! ~SLL
No, the wording of you question is not true. However the movement of the lithospheric plates is related to the formation of volcanoes.
The lithospheric plates are made up of the crust and the uppermost part of the mantle. These plates float on the semi-fluid asthenosphere beneath them.
Tectonic plates are the rigid but moving pieces of Earth's surface that float on the semi-fluid asthenosphere below. These plates interact at plate boundaries, leading to various geological phenomena like earthquakes, volcanic eruptions, and mountain formation.
No, tidal drift is caused by the gravitational pull of the Moon and Sun on Earth's oceans, and it does not directly cause the movement of lithospheric plates. The movement of lithospheric plates is driven by the convection currents in the mantle beneath the Earth's crust.
