How do the lithospheric plates move at a transform margin? Give an example of a present day transform margin

The lithospheric plates constantly float over the layer of the asthenosphere due to the generation of convection current in the mantle. These currents are formed because of the heat that is radiated from the core of the earth.

In a convergent plate boundary, the two plates collides with each other resulting in the formation of a subduction zone that is marked by a deep-sea trench. The magma then rises up towards the surface in the over-riding plate resulting in the formation of volcanoes or a chain of volcanic islands. For example, the San Andes Mountain.

The features that are commonly associated with an oceanic-continental marginal are the subduction zone, trenches and volcanoes or chain of volcanic islands

When two plates slide past one another, then it forms a transform boundary and there occurs no construction or destruction of plates. Shallow focus earthquakes are generated. For example, the San Andreas Fault.
