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 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 when a piece of earths crust is subduction?
When a piece of Earth's crust is subducted, it sinks into the mantle beneath another tectonic plate. This process occurs at convergent plate boundaries, where an oceanic plate often subducts beneath a continental plate due to its higher density. As the subducting plate descends, it can lead to the formation of deep ocean trenches, volcanic activity, and earthquakes. The intense heat and pressure can also cause the subducted material to melt and contribute to magma formation, resulting in volcanic eruptions.
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 when oceanic crust meets with oceanic crust?
When oceanic crust meets another piece of oceanic crust, one of the plates is typically subducted beneath the other due to differences in density. This subduction can lead to the formation of deep ocean trenches and volcanic island arcs. The intense pressure and heat at the subduction zone can also result in geological activity, including earthquakes and the creation of magma that may rise to form volcanic islands. Overall, this interaction plays a crucial role in the dynamics of plate tectonics.
What happens to two oceanic crust when they collide?
the older crust is subducted and later pushed up to form oceanic arcs
What happens to old oceanic crust as molten materials 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 old oceanic crust as new molten material from the mantle?
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.

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.
What happens with a plate of oceanic crust collides with a plate of continental 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.

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.
