transform boundary what happens to the plate, landforms created, example location

Short answer:
- At a transform boundary two plates slide past one another horizontally (shear motion). No significant creation or destruction of lithosphere occurs there, but stress builds and is released as earthquakes.
- Typical landforms: strike-slip faults and linear fault scarps, offset streams/roads/rock layers, linear valleys, sag ponds and pull-apart basins (where bends produce local extension), and pressure ridges or pop-up uplift where bends cause compression. Little or no volcanism.
- Classic examples: San Andreas Fault (Pacific–North American, right-lateral) — offset streams like Wallace Creek and the Carrizo Plain; North Anatolian Fault (Turkey); Dead Sea Transform (left-lateral) producing the Dead Sea pull-apart basin; Alpine Fault (New Zealand); transform faults/fracture zones between mid-ocean ridge segments (e.g., Romanche Fracture Zone in the Atlantic).

A bit more detail:
- Motion type: strike-slip (right-lateral or left-lateral). If the fault has a releasing bend you get extension and basins; a restraining bend gives compression and uplift.
- Hazards: frequent strong earthquakes are the main hazard at transforms.
