Answer:
Lithosphere
Explanation:
The "lithosphere" is made up of the tectonic plates. These plates come from the crust and uppermost mantle of the Earth. It is divided into the Major Plates, Minor Plates and Microplates. The extremely high pressure below causes the rocks in the mantle to melt. These molten rocks cause convection currents resulting to the mantle moving. This then affects the tectonic plates above to move. Such movement is called "plate tectonics."
