The theory of plate tectonics explains the movement of the plates by convection cells in the earth's layers?

TRUE

Explanation:The Theory of PLATE TECTONIC explains the mass movement of Tectonic plates they move or glide over themselves by convection cell,this theory shows that the Earth's surface is divided into layers which are described as plates.

Three forces have been found to be the drivers of Tectonics plates they include

(1) Convection in the Mantle which

is a heat dependent.

(2) Ridge push which is gravitational force dependent,it leads to the spreading of the ridges.

(3) Slab pull which is gravitational force dependent in subduction zones.
