What is volcanic island arc?
I think its a chain of volcanoes form when oceanic crust subducts beneath other oceanic crust on an adjacent plate. Hope this helps (:
How does magma form?
Magma can be formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantle rock.
What is the spatial association and spatial interaction between tectonic plates and volcano locations?
Many volcanos occur along tectonic boundaries, whether they are convergent (pushing together) or divergent (pulling apart). These boundaries typically occur between continental and oceanic plates or between two oceanic plates. Some volcanos however are created by hot spots where molten magma from the mantle of the Earth pushes through the crust, these hot spots can form islands such as the Hawaiian Islands.
How far under the Earth's crust do diamonds form?
About 100 miles
What rocks originate from the surface of the earth?
Sedimentary rocks form on the Earth's crust, and can form metamorphic rocks when buried. Igneous rocks form under the surface, or when liquid magma reaches the surface as lava.
Is the fallowing sentence True or falseHot spots form only under the oceanic crust?
its false
Is the following sentence true or false Hot spots form only under oceanic crust?
false there is a famous hotspot in Yellow stone, CA
How does a deep-ocean trench form?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
How does trench formed?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
How does a trench forms?
They form when the oceanic crust goes under the Continental crust. The oceanic crust then forms the trenches through a process called subduction.
Do hot spots only form in oceanic crust?
No, hot spots can form in both oceanic and continental crust. Hot spots are areas of high volcanic activity that are thought to be caused by a deep-seated mantle plume that rises to the surface, creating a localized area of magma upwelling. These hot spots can create volcanic islands, such as the Hawaiian Islands, regardless of whether they are in oceanic or continental crust.
What is likely to form where oceanic crust is subducted under continental crust?
Where oceanic crust is subducted under continental crust, a trench, volcanic arc, and earthquakes are likely to form. The subduction of the dense oceanic plate causes it to sink beneath the less dense continental plate, leading to the creation of these geological features due to the intense heat and pressure generated in the process.
Plate with oceanic crust sinking under another plate with oceanic crust?
When two oceanic plates or two plates both containing oceanic crust collide or converge, the convergent boundary will form a trench. The plate which has the higher density will plunge beneath the other plate forming a trench.
What happens when oceanic plate and continental plate converge?
As oceanic crust is thinner, it sinks under the continental crust and forms a subduction zone. This can also form a line of volcanoes.a deep sea trench and an island arc form.
What is the plate with oceanic crust sinking under one another plate with oceanic crust?
When one plate sinks under the other, it is callled subduction, no matter what kind of plate it is. When two oceanic plates collide, they form trenches(i.e. the mariana trench). Hope this answers your question!!!
What is form when oceanic crust is pushed under continental crust?
When oceanic crust is pushed under continental crust in a subduction zone, a deep trench is formed at the boundary between the two plates. The oceanic crust then descends into the mantle, creating a convergent plate boundary. This process can lead to the formation of volcanic arcs on the overriding continental plate.
What happens to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
