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.
Geologists think that movement ofconvection currents in the mantle is the major force taht causes plate motion. Suring subduction, gravity pulls one edge of a plate down into the mantle. The rest of theplate also moves This slow movement is similar to what happens in a pot of soup when gravity causes the cooler, denser soup near the surface to sink.
