Active margins, where tectonic plates converge, are characterized by subduction zones where one plate is forced beneath another, leading to the formation of oceanic trenches. These trenches are formed due to the intense geological activity associated with plate interactions, including earthquakes and volcanic activity. In contrast, passive margins, which are not associated with tectonic plate boundaries, lack the necessary geological processes to create such deep oceanic features. Thus, trenches are exclusive to active margins due to their dynamic geological environments.
Trenches are caused by plate movement.
Unlike deep sea trenches which are found in areas where one tectonic plate slides beneath another undersea canyons are found along the slopes of most continental margins the submarine canyons for example tend to have steeper side slopes much higher gradients and considerably narrower floors. thats how they different
coninental trenches are trenches that go across countries...i think

Trenches are caused by subduction.
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.
Trenches are caused by plate movement.
Continental margins near converging plates are often characterized by subduction zones where one plate is forced beneath the other. This leads to the formation of deep ocean trenches and volcanic arcs. Earthquakes and mountain building can also occur along these margins as a result of the intense tectonic activity.
Active continental margins are primarily located along tectonic plate boundaries where oceanic plates are subducting beneath continental plates. These margins are characterized by deep ocean trenches, volcanic arcs, and frequent seismic activity. Examples include the western coast of South America along the Andes Mountains and the Pacific Northwest coast of North America.
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.
Both active and passive margins are found at the edges of continents. Active margins are associated with tectonic activity and are typically marked by earthquakes, volcanoes, and mountain building, while passive margins are geologically stable and characterized by broad continental shelves and sediment deposition.
Subduction. A subduction trench.
No, most ocean trenches (Japan, Mariana, Tonga, South Sandwich, Puerto Rico) are located along the margins of the oceans.
