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.
What else can I help you with?
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
Which of the following is true of passive continental margins?
they have a continental rise
What is usually found at an active margin but NOT at a passive margin?
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.
Are the plate boundaries the same as the edges of continents?
No. Not all plate boundaries are at the edges of continents, nor do all edges of continents correspond with plate boundaries. Many plate boundaries are found in the middle of oceans, while the continent of Africa is being torn apart by a developing plate boundary. Some edges of continents, such as the west coast of South America are near plate boundaries. These are called active continental margins. Others, such as the east coast of North America, are nowhere near plate boundaries. These are called passive continental margins.
Where are broad sediment covered continental shelves found in active pr passive margins?
Broad sediment-covered continental shelves are typically found in passive margins where there is a lack of tectonic activity and the crust is stable. Active margins, on the other hand, are associated with tectonic activity like subduction zones or rift zones, which can result in narrower shelves due to more abrupt changes in the seafloor elevation.
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
What is the difference between a passive continental margin an an active continental margin?
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.
How do active margins differ from passive 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.

What is true about passive continental margins?
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.
During which period was Laurentia completely surrounded by passive margins?
Laurentia was completely surrounded by passive margins during the Neoproterozoic period, approximately 750-600 million years ago. This period saw the formation of the supercontinent Rodinia, where Laurentia was a central part and was surrounded by passive margins as it drifted towards the equator.
What does a passive continental margin have which other margins lack?
A continental rise.
Are the edge of continents the same as the boundaries of plates?
No. Not all plate boundaries are at the edges of continents, nor do all edges of continents correspond with plate boundaries. Many plate boundaries are found in the middle of oceans, while the continent of Africa is being torn apart by a developing plate boundary. Some edges of continents, such as the west coast of South America are near plate boundaries. These are called active continental margins.
