Transform Plate Boundaries In a transform plate boundary (transform fault), plates slide horizontally past one another without producing or destroying lithosphere. They commonly connect 2 spreading centers (divergent), or less commonly 2 trenches (convergent). Mostly found on ocean floor (offset segments of oceanic ridge system, producing a steplike plate margin). Zigzag shape of Mid-Atlantic Ridge reflects shape of original shape of rifting Transform faults are part of linear breaks in seafloor (fracture zones) that include active and inactive (extensions) of the transform faults.
