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.
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.
subduction boundary!!!
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.
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.
It is called subduction and only occurs in oceanic to oceanic or oceanic to continental plate collisions.
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.
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.

Subduction
Convergent oceanic - continental and oceanic - oceanic boundaries.
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.
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.
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.
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.
