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.
What is a continental margin?
A continental margin is the zone of transition between a continent and the deep ocean floor. It includes the continental shelf, continental slope, and continental rise. It is an area where sediments from the continent are deposited and tectonic activity can occur.
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.
When oceanic plunges beneath continental crust volcanic activity and earthquakes may result in which region does this occur?
The continental margins of the Pacific Ocean
Why do most earthquakes occur only in isolated regions?
The west Pacific Ocean earthquakes usually occur along the joins in the continental plates which lie offshore in most cases.
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.
Do the broadest continental shelves occur in the Arctic Ocean?
Arctic ocean
The greatest ocean depths found anywhere occur in ocean what?
pacific
What do more tsunamis occur in the pacific ocean or in the Atlantic ocean?
in the pacific ocean because of the ring of fire (where a lot of active volcanoes are)
Where do most volcanoes occur in the world?
In the "Ring of Fire" on the Pacific Rim (a.k.a. Pacific Ocean)
Most earthquakes occur around the outer edge of what ocean?
The pacific ocean
Would it be more likely for a major explosive eruption to occur at an ocean ridge or at a convergent ocean continental boundary?
it would be more likely to occur at convergent ocean-continental boundary beacuse the rocks are composed with a higher silica and has much thicker continental crust.
