Which of the following is true of passive continental margins?
they have a continental rise
Do active continental margins have a continental rise?
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.
How are continental margins related to mountain building?
Continental margins represent the transition from continental crust to oceanic crust. Mountain building commonly results from the collision of tectonic plates, which can also affect the formation and shaping of continental margins. The processes associated with mountain building, such as subduction and continental collision, can influence the creation and structure of continental margins.
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.
What are Parts of the continental margin?
The three parts of the continental margins are the Continental shelf, the Continental slope, and the Continental rise.
Which seafloor feature is not found on active continental margins?
continental rise
What does a passive continental margin have which other margins lack?
A continental rise.
What seafloor feature is not found on active continental margins?
continental rise
The shallowest parts of the ocean are the?
continental margins
What are the true edges of continents?
The true edges of continents are known as continental margins, which consist of the continental shelf, continental slope, and continental rise. These margins mark the transition from the continent to the ocean basin and can extend hundreds of kilometers from the shoreline.
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
