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 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
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 happends when an oceanic plate goes under a continental plate?
When an oceanic plate goes under a continental plate, the subducting plate ---> oceanic creates a curved line of volcanoes along the edge of the overlying continental plate.
What will happen if a seafloor plate collides with a continental plate?
It will subduct under the less dense continental plate.
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.
These are formed when oceanic plates slide under continental plates?
When oceanic plates slide under continental plates they form subduction zones. Subduction zones always occur at convergent boundaries where one plate slides beneath another plate.
What happens when a plate of oceanic crust collides with a plate of the continental crust and why does this happen?
The oceanic crust will slide under the continental crust. And the reason is because the oceanic crust is much denser and the continental crust is least dense.

When an ocean plate collides with a continental plate it does what?
It subducts under the continental plate because the oceanic plate is denser.
Does an ocean crustal plate rises at a convergent boundary with a continental plate?
No. It subducts under the continental plate.
What will happen if a seafloor plate collides with a continental plate?
It will subduct under the less dense continental plate.

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.
What explains the observation that when a continental and oceanic plate collide the oceanic plate dives down under the continental plate?
The oceanic plate must be more dense than the continental plate for this to happen.
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.
Why is oceanic lithosphere subducted during and oceanic continental collision where as the continental plate is not?
the oceanic plate is less bouyant so it slides under the continental plate
