What else can I help you with?
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.
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.
What are two structures you would find at a passive continental margin that you would not find at an active continental margin?
At a passive continental margin, you would typically find extensive shelf sediments and a broad continental shelf, which accumulate over time due to the lack of tectonic activity. Additionally, features such as deltas and estuaries are common as rivers deposit sediment into the ocean. In contrast, active continental margins are characterized by steep slopes, narrow shelves, and geological features like subduction zones and volcanic arcs, which are not present at passive margins.
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.
Which best explains the absence of volcanoes and earthquakes at a passive continental margin?
A passive continental margin lacks tectonic activity because it is not located near a plate boundary where volcanic and seismic activity typically occurs. Instead, passive margins form as plates pull apart, leading to subsidence and sediment accumulation rather than volcanic eruptions or earthquakes.
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 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 does a active continental margin have that a passive margin does not?
Subduction. A subduction trench.
What does a passive continental margin have which other margins lack?
A continental rise.
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
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.
A passive continental margin has a while an active margin does not.?
An active continental margin may have a trench.
What is a passive continental margin has a what while an active margin does not?
A passive continental margin is characterized by a broad, gently sloping continental shelf and is typically associated with tectonically stable regions, where there is little to no seismic activity. In contrast, an active margin is located near tectonic plate boundaries and is marked by significant geological activity, including earthquakes and volcanic activity. Essentially, a passive margin has a well-defined continental shelf and a lack of tectonic activity, while an active margin does not.
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.
When A passive continental margin has a while an active margin does not.?
A passive continental margin is not tectonically active, meaning it does not experience significant geological activity like earthquakes or volcanic eruptions. In contrast, an active continental margin is located near a tectonic plate boundary, leading to geological activity such as subduction zones, earthquakes, and volcanic eruptions.
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.
