Definition "Plate tectonics" ( from the Greek │∣│ = builder) refers to the theory describing the motion of the plates, 100–200 km thick, which form Earth's lithosphere . These rigid plates, which consist of continental or oceanic crust underlain by lithospheric mantle , are displaced ...
The meaning of PLATE TECTONICS is a theory in geology: the lithosphere of the earth is divided into a small number of plates which float on and travel independently over the mantle and much of the earth's seismic activity occurs at the boundaries of thes
