What else can I help you with?
Can the oceanic crust be destroyed?
Subduction
Is oceanic crust slide under oceanic crust during subduction?
Yes, oceanic crust can slide under oceanic crust during subduction at convergent plate boundaries. This process occurs when a more dense oceanic plate descends beneath another oceanic plate, leading to the formation of a subduction zone.
Differences between oceanic-oceanic and oceanic-continental subduction boundary?
In an oceanic-oceanic subduction boundary, one oceanic plate subducts beneath another oceanic plate. This process can result in volcanic island arcs being formed. In an oceanic-continental subduction boundary, an oceanic plate subducts beneath a continental plate. This can lead to the formation of volcanic mountain ranges on the continental plate.
What is it called when one plate is pushed under another plate as the collide?
subduction boundary!!!
What is the process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary called?
The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary is called subduction. This occurs because oceanic crust is denser than the underlying asthenosphere, causing it to be pulled down into the mantle. Subduction zones are associated with the formation of volcanic arcs and deep-sea trenches.
Why do continents generally not subduct beneath oceanic plates?
Continents generally do not subduct beneath oceanic plates because continents are less dense and thicker than oceanic plates. This makes them more buoyant and resistant to being forced downward into the Earth's mantle. Additionally, the composition and structure of continents make them less likely to be pulled into subduction zones.
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 is Japan on the border of?
It is on the northeast border of the Pacific Ocean, on the so-called "Ring of Fire" created by the subduction of oceanic crust along the borders of continents.
What process when the ocean floor and the continents go towards each other?
The process is called subduction, where the heavier oceanic plate is forced beneath the lighter continental plate due to their movement towards each other. This can lead to the formation of deep oceanic trenches and volcanic activity at the subduction zones.
What is oceanic-oceanic subduction?
Oceanic crust sinking under a plate with continental crust
Can the oceanic crust be destroyed?
Subduction
What type of boundaries are subduction zones associated with?
Convergent oceanic - continental and oceanic - oceanic boundaries.
During the collision between two continents why doesnt a subduction zone form?
Generally, subduction zones are formed when two plates collide and one is heavier than the other. When two continents collide, rather than one sinking, they will both be uplifted because they are light and buoyant.
Is oceanic crust slide under oceanic crust during subduction?
Yes, oceanic crust can slide under oceanic crust during subduction at convergent plate boundaries. This process occurs when a more dense oceanic plate descends beneath another oceanic plate, leading to the formation of a subduction zone.
The process of an oceanic plate colliding with and descending underneath a continental plate?
This process is known as subduction. When an oceanic plate collides with and is forced underneath a continental plate, it creates a subduction zone. The descending oceanic plate melts due to the intense heat and pressure, causing volcanic activity and the formation of mountain ranges on the continental plate.
Why do continents not go down subduction zones?
Partly because continental crust is less dense and more buoyant than oceanic crust, so it won't sink down subduction zones, and partly because it's much thicker than oceanic crust and buckles in plate collisions rather than subducts.
Why don't continents go down subduction zones?
Continents are made of continental lithosphere. Continents are composed of rocks that are more buoyant their than denser oceanic counterparts. These lighter rocks float on top of the asthenosphere, which is denser. This balance is maintained due to the fact that lighter substances will raise and rest on heavier substances, such as the asthenophere
