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.
The ocean floor is divided into two major regions?
The ocean floor is divided into two major regions: the continental margin, which includes the continental shelf, slope, and rise, and the deep ocean basin, which includes abyssal plains, seamounts, trenches, and mid-ocean ridges. These regions have distinct geological features and play important roles in shaping the Earth's surface.
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.
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.
Is the west coast of Africa a passive or active continental margin?
Passive continental margin.
What does a active continental margin have that a passive margin does not?
Subduction. A subduction trench.
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 coninental margin?
A subduction zone would be found at an active continental margin, where one tectonic plate is being forced beneath another. This process leads to features such as deep ocean trenches, volcanic arcs, and earthquakes. In contrast, passive continental margins lack these tectonic interactions and are characterized by a relatively smooth transition from continent to ocean basin.
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.
A passive continental margin has a while an active margin does not.?
An active continental margin may have a trench.
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.
What does the passive continental margin have that the active margin does not?
Subduction. A subduction trench.
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.
The east coast of North America is an example of what kind of margin?
Passive
What does a passive continental margin have which other margins lack?
A continental rise.
Which South American continental margin is passive and not a plate boundary?
The east coast of South America along the Atlantic Ocean is a passive continental margin. This means that it is not located along a tectonic plate boundary where significant tectonic activity such as earthquakes or volcanic eruptions occur. The passive margin formed when South America separated from Africa during the opening of the South Atlantic Ocean.
