This is because the land mass is more buoyant, or lighter, than the ocean
floor.

Why does ocenaic crust sink beneath the continental crust at a subduction boundary?

Oceanic crust is denser than continental crust due to its composition of basaltic rock and higher iron content. This density difference causes oceanic crust to sink beneath the lighter continental crust at subduction zones, creating a convergent boundary. The descending oceanic plate creates deep oceanic trenches and can trigger volcanic activity when it melts and rises to the surface.


Why oceanic crust is always subducted underneath continental crust?

Oceanic crust is denser than continental crust, so when they collide, the denser oceanic crust is forced beneath the lighter continental crust in a process known as subduction. This subduction occurs at convergent plate boundaries where two plates are moving towards each other. The sinking oceanic crust can trigger volcanic activity and create mountain ranges on the continental crust.


What are two kinds of crust involved in a subduction zone?

Both continental and oceanic crusts are used in the process of subduction, unless you are talking about see floor spreading, then only oceanic crust is used


When continental plates collide what happens to the oceanic crust between them?

When continental plates collide, the denser oceanic crust is usually subducted beneath the less dense continental crust. This process can create subduction zones, where the oceanic crust is forced downward into the mantle. The oceanic crust may melt or be recycled back into the mantle in these subduction zones.


When a continental crustal plate collides with an oceanic crustal plate the continental crust is forced to move over the oceanic crust What is the primary reason that the continental crust stays on?

The continental crust is less dense and thicker than oceanic crust, which allows it to stay on top during a collision. The low density and greater thickness of continental crust help it resist subduction beneath the oceanic crust.

When continental crust and oceanic crust collide which one will subduct?

Oceanic crust is denser than continental crust, so when they collide, the oceanic crust will subduct beneath the continental crust. This subduction process can lead to the formation of volcanic arcs and mountain ranges.


What happens when an oceanic plate collides with a continental plate?

when oceanic crust and continental crust collide, the oceanic crust sinks down beneath the continental crust. this is called subduction.


What is the process by which oceanic crust sinks beneath the trenches?

Oceanic crust sinks beneath trenches through a process known as subduction. As oceanic plates collide with continental plates, the denser oceanic plate is forced downward into the mantle due to gravitational pull. This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.

Oceanic crust sinking under a plate with continental crust

What happens when oceanic and continental crust meets?

When oceanic and continental crust meet, a subduction zone is formed where the denser oceanic crust is forced beneath the less dense continental crust. This process typically results in the formation of deep ocean trenches, volcanic arcs, and earthquakes.


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.
