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.
Which part of the continental margin is missing in an active continental margin?
In an active continental margin, the continental slope is typically more pronounced, and the continental rise is often absent or minimal. This is because active margins are associated with tectonic plate boundaries, where subduction occurs, leading to steep, rugged coastlines and a lack of sediment accumulation that would typically form a continental rise. Instead, the ocean floor is characterized by deep ocean trenches and volcanic arcs.
How do you label continental margin?
Continental margins can be labeled as either active or passive. Active margins are typically found along tectonic plate boundaries, featuring steep coastlines, narrow continental shelves, and significant geological activity such as earthquakes and volcanic activity. In contrast, passive margins are located along stable tectonic plates, characterized by broader continental shelves, gentle slopes, and less geological activity. Each margin type can further be divided into sub-zones, including the continental shelf, slope, and rise.
The narrow continental margin of the?
The narrow continental margin is typically found along passive continental margins, where the continental shelf is relatively small and steep. This type of margin is characterized by a gentle slope leading to the continental slope, followed by the continental rise and then the abyssal plain. Such margins often have limited sediment accumulation and are less tectonically active compared to wider margins. They play a crucial role in marine ecosystems and can influence ocean circulation patterns.
Is the continental margin of fort Myers an active continental margin?
No, the continental margin of Fort Myers is not considered an active continental margin. Active continental margins are typically associated with tectonic activity, such as subduction zones or plate boundaries, which are not present in the area surrounding Fort Myers.
Which seafloor feature is not found on active continental margins?
continental rise
What seafloor feature is not found on active continental margins?
continental rise
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
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 does a passive continental margin have which other margins lack?
A continental rise.
What true of passive continental margins?
they have a continetal rise (
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.
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.
List the subdivisions of the continenal margin?
The three parts of the continental margins are the Continental shelf, the Continental slope, and the Continental rise.
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.
