What is likely to form where oceanic crust is subducted under continental crust?
because oshieotic crust is under Mantle is thicker
Is it true that hotspots form where a plume of magma rises through the crust from mantle?
True
Description of oceanic-oceanic subduction?
Occurs when ocean crust sinks under continental crust, it sinks because it's colder and denser,at these sites, deep-ocean trenches also form along with coastal mountains. As the oceanic crust moves, these trenches often causes underwater earthquake, as the crust sinks under a continent, the crust buckles to form a range of mountains, like island arcs, parallel to a deep-ocean trench. Some of the mountains are volcanoes, which form as melted oceaninc crust rises through the top plate. For example: Cascade Mountains in Oregon and Washington.
Where did the crust from the earth come from?
The Earth some times oceanic crust is formed by the process of mid oceanic ridges. this process occurs when magma comes from the mantle and cool below oceanic body & form new crust.
Why do deep-ocean trenches form at both types of subduction?
The deepest portions of the subducting plate get pulled under by the subducted plate. This is how the trench is formed. this process is at work when any subduction occurs. An oceanic-continental subduction occurs when ocean crust sinks under continental crust. The oceanic crust sinks because it is colder and denser than the continental crust. At these sites, deep-ocean trenches form, along with coastal mountains.
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.

A 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.
Do hot spots form only under oceanic crust?
No, there is a hot spot underyellowstone
Is the fallowing sentence True or falseHot spots form only under the oceanic crust?
its false
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 form when oceanic crust is pushed under continental crust?
Trenches. An example would be the deepest point of the ocean in the world, which is a trench in Japan.
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 happens to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
