(From Tempur-Pedic's Website) Tempur-Pedic mattresses have been designed to be paired with a Tempur-Pedic foundation. However, we understand that some consumers wish to use their existing platform style bed with slats (as opposed to a flat surface) with our mattress.
The type of motion along a fault depends on the type of fault. The main types of faults are described below. 1  Normal dip-slip fault. 2  Normal faults happen in areas where the rocks are pulling apart (tensile forces) so that the rocky crust of an area is able to take up more space. 3  The rock on one side of the fault is moved down relative to the rock on the other side of the fault.
With both normal and reverse faults, movement occurs vertically. A normal fault is usually associated with plates that are diverging. Tension weakens the crust until the rock fractures, and one block of rock moves downward relative to the other. A reverse fault is usually associated with plates that are colliding. Compression forces a fault block upward. A thrust fault is a special kind of reverse fault where one or more plates are under the ocean. At a thrust fault, a plate below the sea is moving under another plate, thrusting its edge upward. The process of one plate diving under the other is called subduction. Thrust faults can produce larger earthquakes than strike-slip faults.
