The transform faults are faults were the motion is mostly horizontal, they happen often in the ocean ridge. It´s when two plates move horizontally from eachother and that causes a fault, one of the most known transform fault is the fault of San Andreas, in California, but most of this kind of faults occur on the ocean basis.
