More About Network Cabling. The most commonly used types of network cable are the twisted pair, coaxial, Ethernet cross over, and fiber optic. The unshielded twisted pair (UTP) cable is used in many Ethernet networks. It has four pairs of wires that are housed inside of the lining of the cable.
Trench Suction. A third force that forms as a result of plate movement is known as trench suction. As a plate gets pushed back into the mantle (as we saw in slab pull), it is forced down at an angle. Not only does gravity pull it down in the slab pull model, but another force can act on it as well.
Plate tectonics is the name given to the forces that drive plate  motion. Scientists don't know what causes the natural phenomenon of  plate tectonics.
