What else can I help you with?
Is the west coast of Africa a passive or active continental margin?
Passive continental margin.
What can you find on a passive continental margin but not a active continental margin?
On a passive continental margin, you can find thick sedimentary layers, wide continental shelves, and less seismic activity compared to an active continental margin.
What does a passive continental margin have which other margins lack?
A continental rise.
What are two structures you would find at a passive continental margin?
At a passive continental margin, you would find a continental shelf, which is the shallow, relatively flat platform extending from the shoreline, and a continental slope, which is a steeply sloping transition zone between the continental shelf and the deep ocean floor.
Which of the following is true of passive continental margins?
they have a continental rise
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
Which is found far inland?
either active continental crust or passive continental crust.
What is one structure you would find at an active continental margin that you would not find at a passive continental margin?
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.
What true of passive continental margins?
they have a continetal rise (
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.
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.
Are the Appalachian mountains on an active plate edge?
No. There is no such thing as a passive plate edge. They are near a passive continental margin.
