An active continental margin may have a trench.
On an active continental margin, you would be likely to find an active ocean trench. This structure would generally not occur at a passive continental margin.
You will find active faults and, if the margin is convergent, volcanoes.
Active and passive margins describe the various characteristics of continental margins that are a result of plate tectonics. An active margin usually has numerous volcanoes and mountains, while a passive margin typically do not have these formations.
