No, active continental margins typically do not have a continental rise. Instead, they often have a steep continental slope that descends into a deep oceanic trench due to tectonic activity. Continental rises are found at passive continental margins where there is minimal tectonic activity.
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.

Subduction. A subduction trench.
Passive continental margins are not tectonically active, meaning there is no significant seismic activity or mountain-building processes occurring there. They are typically characterized by a wide continental shelf and a gentle slope leading to the ocean basin. Sediment accumulation is common along passive continental margins due to lower energy conditions compared to active margins.

Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
At a passive continental margin, you would typically find extensive shelf sediments and a broad continental shelf, which accumulate over time due to the lack of tectonic activity. Additionally, features such as deltas and estuaries are common as rivers deposit sediment into the ocean. In contrast, active continental margins are characterized by steep slopes, narrow shelves, and geological features like subduction zones and volcanic arcs, which are not present at passive margins.
An active continental margin may have a trench.
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.
Yes. Earthqyakes are common at active continental margins.
