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 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.
Is lithosphere crust destroyed in convergent boundaries?
Yes, in convergent boundaries, lithosphere crust can be destroyed. When two tectonic plates collide, typically an oceanic plate subducts beneath a continental plate or another oceanic plate, leading to the bending and melting of the subducted crust. This process can result in the formation of deep ocean trenches and volcanic arcs, effectively recycling the lithosphere into the mantle.
Which boundary destorys the crust?
Subduction boundaries, where one tectonic plate is forced below another, can destroy crust as the subducting plate melts and is absorbed into the mantle. This process can lead to the recycling of crustal material back into the Earth's interior.
When is earths Crust destroyed?
The Earth's crust is destroyed when subduction occurs.
What happens to the earth's crust that is subducted?
When the Earth's crust is subducted, it sinks into the mantle at convergent plate boundaries, where one tectonic plate moves beneath another. This subduction process leads to increased temperature and pressure, causing the crust to partially melt and contribute to magma formation. The materials from the subducted crust can also lead to volcanic activity and the creation of mountain ranges over geological time. Eventually, some of the subducted material may be recycled back to the surface through volcanic eruptions or tectonic uplift.

What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
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.
When new crust is made what happens to the old crust?
When new crust is made, like at a spreading center, old crust must be destroyed, like at a subduction zone, where it is brought back into the inner earth and melted and recycled through.
Is lithosphere crust destroyed in convergent boundaries?
Yes, in convergent boundaries, lithosphere crust can be destroyed. When two tectonic plates collide, typically an oceanic plate subducts beneath a continental plate or another oceanic plate, leading to the bending and melting of the subducted crust. This process can result in the formation of deep ocean trenches and volcanic arcs, effectively recycling the lithosphere into the mantle.
When Crust is destroyed.?
The Earth's crust is destroyed when subduction occurs.

Why havent older ocean rocks been discovered?
Oceanic crust is eventually destroyed in subduction zones. Although oceanic crust has been forming on Earth for over 4 billion years, all of the sea floor older than about 200 million years has been recycled by plate tectonics. Continental crust is not subducted and destroyed, so very old continental rocks have survived.
When is earths Crust destroyed?
The Earth's crust is destroyed when subduction occurs.

Old ocean floor is destroyed and absorbed by the Earth and remelted beneath what?
Old ocean floor is destroyed and absorbed by the Earth at subduction zones, where tectonic plates collide and one plate is forced beneath the other. The remelting occurs beneath volcanic arcs, where the subducted crust melts and rises to the surface as magma, leading to the formation of new crust.
What happens to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
