It depends of the ocean between 3000 & 33000 metets
What else can I help you with?
Deep-oceanic trenches are most abundant around the rim of the?
Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone.
What is an oceanic deep?
a dip in the sea BED
When two oceanic plates collide it creates?
when two oceanic plates collide they create a deep-ocean trench, at deep-ocean trenches subduction occurs.
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
Oceanic crust returns to the mantle at deep ocean trenches which are?
rocks
Where oceanic crust sinks toward the mantle beneath continental crust a deep ocean?
A deep oceanic trench forms where oceanic crust subducts beneath continental crust. The descending oceanic plate melts as it reaches greater depths, creating magma that can lead to volcanic activity. This process can also generate earthquakes due to the intense pressure and stress in the subduction zone.
Is the absence of deep focus earthquakes along the oceanic ridge system is inconsistent with the theory of plate tectonics?
No, the absence of deep focus earthquakes along the oceanic ridge system is not inconsistent with the theory of plate tectonics. Deep focus earthquakes typically occur in subduction zones, where one tectonic plate is sinking beneath another. Oceanic ridges are areas where new oceanic crust is formed and plates are moving apart, which does not typically generate deep focus earthquakes.
Convergence can occur between what types of plates?
Convergence can occur between oceanic-oceanic, oceanic-continental, and continental-continental plates. This process typically leads to the formation of mountain ranges, deep ocean trenches, and volcanic arcs.
At deep-ocean trenches what allows oceanic crust to sink back into the mantle?
Subduction.
What is the process where oceanic crust is sinking under continents at deep ocean trenches?
Sinkation
Which feature is commonly formed at a plate boundary where oceanic crust converges with continental crust?
A deep ocean trench is commonly formed at a plate boundary where oceanic crust converges with continental crust. The oceanic crust is denser and is forced beneath the lighter continental crust, creating a deep trench.
Convergent oceanic oceanic definition?
Convergent oceanic-oceanic boundaries occur when two oceanic plates collide. One plate is usually subducted beneath the other, leading to the formation of deep ocean trenches and volcanic island arcs. This process can result in intense geologic activity, such as earthquakes and volcanic eruptions.
