Why is the oceanic crust pushed under the continental plate?
The oceanic crust is pushed under the continental plate due to its higher density compared to the less dense continental crust. This process occurs at convergent plate boundaries, where tectonic plates collide. The denser oceanic plate subducts beneath the continental plate, leading to geological phenomena such as earthquakes and the formation of mountain ranges. Subduction zones are also associated with volcanic activity as the descending oceanic crust melts and can trigger magma formation.
Why does the oceanic sink beneath continental crust at convergent boundaries?
The continental crust is less dense than the oceanic crust. That's the reason we find that the oceanic crust sinks (subducts) beneath the continental crust.Continental crust is less dense than oceanic crust and so cannot sink below it.
How oceanic crust different?
Oceanic and Contintental crust are different in composition as well as size and density Continental- granitic/50-100km thick Oceanic- basaltic/ up to 10km thick Oceanic crust is more dense making it subduct under continental crust
When a more dense oceanic plate sinks under continental plate?
This is called a destructive plate boundary. It occurs due to the fact that the oceanic crust is far denser than the continental crust. As a result it subducts into the mantle and is incenerated. Hope it helped:)
What is the difference between the thickness of the continetal crust and oceanic crust?
In technical terms, the oceanic crust is denser than the continental crust so when the continental crust and the oceanic crust meet the continental crust will sink under and the oceanic crust will slide over and a volcano will be formed as well as producing earthquakes in the process.
What is form when oceanic crust is pushed under continental crust?
When oceanic crust is pushed under continental crust in a subduction zone, a deep trench is formed at the boundary between the two plates. The oceanic crust then descends into the mantle, creating a convergent plate boundary. This process can lead to the formation of volcanic arcs on the overriding continental plate.

When an oceanic plate is pushed under a continental plate resulting in volcanic activity this type of boundary forms?
A subduction zone is formed when an oceanic plate is pushed under a continental plate, resulting in volcanic activity. Oceanic crust is denser and sinks beneath the less dense continental crust, leading to the formation of volcanic arcs on the overriding plate.
What is oceanic-oceanic subduction?
Oceanic crust sinking under a plate with continental crust
How do the oceanic and continental crust differ?
Because the oceanic crust is under water in the ocean and a continental crust is land such as the continents
What means the ocean is pulled under the continent?
The ocean is never pulled under the continent. Oceanic crust--the rock and some sediments, however, slide under the edges of continental crust and are pushed downward toward the mantle in areas of oceanic to continental plate collisions.
What is oceanic and oceanic?
The continental crust is the land. The oceanic is under the ocean.
Oceanic crust slides under continental crust during subduction because oceanic crust is?
denser
Oceanic crust slides under continental crust during subduction because oceanic crust is .?
denser (Apex)
What happens when a plate of oceanic crust collides with a plate of the continental crust and why does this happen?
When oceanic crust collides with continental crust, the denser oceanic crust is forced beneath the continental crust in a process called subduction. This happens because oceanic crust is heavier, colder, and more dense than continental crust, making it susceptible to being subducted under the lighter continental crust. This collision can result in the formation of mountain ranges, volcanic arcs, and deep ocean trenches.
What do one oceanic and one continental crust produce when the oceanic crust is subducted under the continental one?
A trench and a strata volcano.
Why is oceanic crust subducted under continental crust?
Continental crust is less dense and cooler than oceanic crust and less dense and cooler than the asthenosphere, therefore instead of subducting, it is pushed upward in a collision between continents, or floats over a subducting oceanic crust.
