When does a part of oceanic plate sink into the mantle?

Usually when it meets another tectonic plate at a convergent plate boundary. If the oceanic plate converges with a continental plate the denser oceanic plate will be forced under the continental plate. If it converges with another oceanic plate the older (and therefore cooler and denser) plate will be forced under the younger plate.


What causes some oceanic plates to sink and others to float?

Oceanic plates sink because they are denser than the underlying mantle, due to cooling and becoming more compact over time. In contrast, other plates float because they are less dense than the mantle material below, allowing them to remain buoyant on top.


What ocean plate and continental plate colliding?

At this type of convergent boundary the oceanic plate will be subducted, or sink into the mantle underneath the continental plate. Volcanoes often form near these boundaries.


At deep ocean trenches what allows oceanic crust to sink back into the mantle?

Conduction. Heat istransferred from the mantle to the crust, melting it to become part of the mantle.


Which direction does the Benioff Zone descend from the trench into the mantle?

The Benioff Zone descends from the trench into the mantle in a downward and inclined direction. This zone is where the descending oceanic plate bends and begins to sink into the mantle beneath the overriding plate.


When a continental plate and an oceanic plate collide why does the oceanic plate sink below the continental plate?

The oceanic plate is denser than the continental plate due to its composition of heavier mafic rock. This density difference causes the oceanic plate to sink below the continental plate in a process known as subduction.


Cooler older oceanic lithosphere sink into the mantle at?

Cooler, older oceanic lithosphere sinks into the mantle at subduction zones where two tectonic plates converge. As the denser oceanic plate descends into the mantle, it creates deep ocean trenches and may eventually cause volcanic activity. This process is essential for the recycling of oceanic crust and plays a key role in plate tectonics and the Earth's geological processes.


Is there magnetic strips on the ocean floor are places where oceanic crust sink back to the mantle?

Is there magnetic stripe son the ocean floor are places where oceanic crust sink back to the mantle


Why do oceanic plates dive underneath continental plates when they collide?

this is because the oceanic plate is much denser than the continental plate so when they collide the oceanic plate will sink easily


Do seafloor plates collide?

Technically, yes. At convergent boundaries, an oceanic plate will subduct, or sink, under a continental plate and melt back into the mantle. An example of this is the Juan De Fuca plate, which has almost been entirely subducted under the North American Plate.


At deep-ocean trenches what allows oceanic crust to sink back into the mantle?

Subduction.


Do magnetic stripes on the ocean floor oceanic crust sink back into the mantle?

No, the magnetic stripes on the ocean floor form due to the alignment of magnetic minerals in the crust as it solidifies from the mantle. The oceanic crust is eventually consumed in subduction zones and recycled back into the mantle, but the magnetic stripes themselves do not sink back into the mantle.
