Subducted oceanic crust refers to the portion of the Earth's oceanic lithosphere that is forced beneath another tectonic plate into the mantle at convergent plate boundaries. This process occurs because oceanic crust is denser than continental crust, causing it to sink when the two plates collide. As the oceanic crust subducts, it can lead to geological phenomena such as the formation of deep ocean trenches, volcanic arcs, and earthquake activity. The subduction process also contributes to the recycling of materials within the Earth's interior.

When does a plate carrying continental crust converges with a plate carrying oceanic crust?
When a plate carrying continental crust converges with a plate carrying oceanic crust, the denser oceanic plate is typically subducted beneath the less dense continental plate. This can lead to the formation of volcanic arcs and deep ocean trenches.
Why does oceanic crust subducted when it collides with a continental plate?
Oceanic crust subducts when it collides with a continental plate primarily due to its higher density compared to continental crust. The denser oceanic plate is forced beneath the lighter continental plate at convergent boundaries, creating a subduction zone. This process leads to geological phenomena such as earthquakes and volcanic activity, as the subducted oceanic crust melts and interacts with the mantle.
What is crust subducted and destroyed at?
Crust is subducted and destroyed at convergent plate boundaries, where one tectonic plate is forced beneath another. This process typically occurs at oceanic-continental or oceanic-oceanic boundaries, leading to the formation of deep ocean trenches and volcanic arcs. As the subducted plate descends into the mantle, it melts and contributes to geological phenomena such as earthquakes and volcanic activity.
Where the crust is subducted and destroyed?
The crust is subducted and destroyed at convergent plate boundaries, where an oceanic plate collides with a continental plate or another oceanic plate. In these zones, the denser oceanic plate is forced beneath the lighter continental crust into the mantle, leading to volcanic activity and the formation of deep ocean trenches. As the subducted material melts and is recycled, it contributes to geological processes such as magma formation and the creation of mountain ranges.
What happens to the old oceanic crust as new molten material rises from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
What happens to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
What do one oceanic and one continental crust produce when the oceanic crust is subducted under the continental one?
A trench and a strata volcano.
Why is oceanic crust younger than the continental crust?
oceanic crust is constantly being subducted and replaced with new material at places like the mid Atlantic ridge.
Why oceanic crust is always subducted underneath continental crust?
Oceanic crust is denser than continental crust, so when they collide, the denser oceanic crust is forced beneath the lighter continental crust in a process known as subduction. This subduction occurs at convergent plate boundaries where two plates are moving towards each other. The sinking oceanic crust can trigger volcanic activity and create mountain ranges on the continental crust.
Convegent boundarie what changes to the crust occur?
The crust is compressed into mountains (if it is continental crust) or subducted back into the mantle if it is oceanic crust.

What happens when a plate of oceanic crust collides with a plate of oceanic crust?
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.
