The Divergent plates move apart letting magma in. The type of stress is Tension. The landforms are distinct.
Transform plate boundaries type of stress is shear. Landforms created by shear stresses are not as obvious as landforms created by tension or compression. The plate boundaries form perpendicular to mid-ocean ridges.
The convergent plates move together.The type of stress is Compression. The type of landform depends on whether the plates are oceanic or continental.
