Because magma rises through hot spots( holes in the ground on the ocean floor) and cools forming new crust which repeats over hundreds of years making the oceanic crust more dense than continental crust. Since the oceanic crust is more dense, it sinks faster causing it to slide under the continental crust
What else can I help you with?
Which convergent plate boundry does not include a subduction zone and why?
The plate boundary is continental - continental. This creates mountains and earthquakes, but one plate doesn't go under the other
What type of boundary forms when an oceanic plate is pushed under a continental plate?
A convergent boundary forms when an oceanic plate is pushed under a continental plate. This process, known as subduction, can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.
When one oceanic plate and a continental plate collide?
The oceanic plate is made of denser (and thinner) rock than the continental crust, so the oceanic plate gets subducted (pushed underneath) where it descends and gets melted by geothermal heat.
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 happends when an oceanic plate goes under a continental plate?
When an oceanic plate goes under a continental plate in a process called subduction, the oceanic plate is forced down into the mantle due to its higher density. This creates a subduction zone where the oceanic plate melts and forms magma, leading to volcanic activity. The continental plate is usually uplifted, creating mountain ranges.
These are formed when oceanic plates slide under continental plates?
Subduction zones are formed when oceanic plates slide beneath continental plates. The process leads to the oceanic plate being forced into the Earth's mantle. This can result in the formation of deep oceanic trenches and volcanic activity at the surface.

Does an ocean crustal plate rises at a convergent boundary with a continental plate?
No. It subducts under the continental plate.

Does plate slide under another plate at a divergent plate boundary?
Yes it does!
What happens to points along the pacific ring of fire?
Various things happen along the Pacific ring of fire. In places the Pacific Plate slides alongside a Continental Plate. It does not slide smoothly but jerks. When that happens, an earthquake occurs. In other places it slides underneath a Continental Plate. That can lead to an earthquake. When it slides under land, it can lead to a volcano. When it slides under the ocean it can cause a Tsunami. In some places the plate has been still for centuries.
What occurs when a continental and an ocean plate collide?
The oceanic plate goes under the continental plate and into the mantle in a process known as subduction. This results in the formation of mountains and volcanoes on the continental plate.
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.

When an oceanic plate goes under a continental plate in a process called subduction, the oceanic plate is forced down into the mantle due to its higher density. This creates a subduction zone where the oceanic plate melts and forms magma, leading to volcanic activity. The continental plate is usually uplifted, creating mountain ranges.
What is the effect when a oceanic plate meets a continental plate?
the oceanic plate subducts under the continental plate and then melts in the mantle and often will create volcanos along the conitinental plate.\
