What forms when one oceanic plate is forced beneath another plate a rift valley an ocean basin an ocean ridge a subduction zone?
a subduction zone
What is it called when one oceanic plate is forced beneath another plate?
Subduction.This specific process occurs at a destructive plate margin.The oceanic plate subducts at around 25-45 degrees into the mantle and the friction produced between the two plates triggers earthquakes.
Where is the oceanic crust sinking into 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.
The process of an oceanic plate colliding with and descending underneath a continental plate?
The oceanic crust is subducted underneath the continental crust. This process is known as subduction.
Why does one plate sink beneath another at a subduction boundary?
This is because of the differing densities of the two types of plate. Oceanic plates are composed of mafic rocks which have higher concentrations of iron and magnesium than the silica and aluminum rich rocks of the crustal plates. This concentration of iron and magnesium makes the oceanic crust more dense than the continental crust and so the oceanic crust tends to be forced under the continental crust at a subduction zone.

When 1 plate is forced beneath another?
Subduction
What are the types of collisions that happen at convergent boundaries?
Subduction (where one plate is forced beneath another less dense plate - may occur at oceanic-oceanic and oceanic-continental boundaries), obduction (where oceanic plate is forced over a continental plate) and orogenesis where two continental plates collide and mountains are formed (e.g. the Himalayas).
Process where one of Earth's plates is forced beneath the edge of another?

What takes place when one plate is forced down into the mantle beneath another plate?
Subduction! :)
What boundary is it when 2 oceanic plates move under each other?
The boundary is known as the Subduction Zone. One plate is forced down beneath the other and into the mantle.

Does subduction create or destroy oceanic crust?
In a subduction zone the crust is forced inot the mantle where it is eventually melted and destroyed
