What forms where an oceanic plate begins to move down in a subduction zone?
Convergent Boundaries
Were does subduction take place?
Subduction occurs when an oceanic plate slides under a continental plate. When the oceanic plate does this, it descends into the mantle, and the place where the subduction begins forms a deep-ocean trench.
What is the name of the process where ocean crust sinks back toward the mantle?
It is called subduction and only occurs in oceanic to oceanic or oceanic to continental plate collisions.
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 boundary is it called when an oceanic plate descends beneath a continental plate?
It's called destructive plate margin/boundary, or convergent plate margin though this term applies to all plate margins where two plates are moving towards each other (such as continental + continental or oceanic + oceanic).
What is it called when one plate is pushed under another plate as the collide?
subduction boundary!!!
What type of boundary forms when an oceanic plate is pushed under a continental plate?
a convergent boundary. The oceanic plate is then subducted under the continental plate because it is denser. This subduction creates earthquakes and volcanoes
Aera where an oceanic plate goes down into the mantle?
A subduction zone at a convergent plate boundary. Undersea trenches are formed where the oceanic plate subducts, and volcanism and earthquakes may result from the partial melting and downward movement of the subducting crust.
What forms when one oceanic plate is forced beneath another plate a. an ocean basin b. an ocean ridge c. a subduction zone d. a rift valley?
C. subduction zone
What is oceanic-oceanic subduction?
Oceanic crust sinking under a plate with continental crust
what are examples for subduction?
An oceanic plate can descend beneath another oceanic plate - Japan, Indonesia, and the Aleutian Islands are examples of this type of subduction. Alternately, an oceanic plate can descend beneath a continental plate - South America, Central America, and the Cascade Volcanoes are an example of this type of subduction.
What deep-ocean feature forms at subduction zones?
In a subduction zone an oceanic plate slides under a continental plate or another oceanic plate. The subduction plate introduces water into the mantle, lowering melting temperatures and generating magma. This causes volcanoes, usually stratovolcanoes, to form on the overriding plate. If the overriding plate is continental a mountain range may develop.
