The plates are moved by convection currents in the mantle.
Oceanic plates are mainly composed of basalt or chemically similar rocks. These are more dense than most of the rocks of continental plates so, when the two collide, the denser plate will be overridden by the other and subducted.
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 are plates moving away from one Another?
When plates move towards each other it is called a convergent boundary. The two types of plates converging depends on what happens. When it is oceanic/oceanic, both plates subduct (go downward), leading to the creating of trenches found at the depths of the ocean. When an oceanic plate converges with a continental plate, the more dense oceanic plate subducts under the continental plate, again creating trenches, and also leading to the destruction of the ocean floor. When continental plates converge, they tend to smash up and rise, creating mountains. When plates move apart, it is called a divergent boundary. When oceanic plates move apart, magma rises, cools, and solidifies to create new ocean floor. This, along with continental/oceanic convergence, accounts for seafloor spreading. When two continental plates diverge, the area left between them slowly turns into an ocean. For an example of this type of ocean, look at the Red Sea.
What is the underwater edge of a continent called?
You can't have a continent rise from land, but you can have land rise from the continental shelf, which may be under water, and that is called an island.
When two plates collide what determines which plates comes out on top?
The more dense plate subducts (goes under) the less dense plate. For example if continental and oceanic crust collide oceanic crust will go underneath the continental.
How do the mountains that form along an oceanic oceanic convergent boundary differ from those associated with an oceanic continental convergent boundary?
the oceanic plates are denser than continental plates, therefore, when oceanic plates and continental plates converge, the oceanic will go under the continental plates. But when two oceanic converge either both will rise to form moutains, or both will sink and cause a trench.
What features form when a continental plate collides with an oceanic plate?
When an ocean plate collides with a continental plate, a subduction zone occurs and forms a deep trench. An ocean plate is more dense while a continental plate is less dense which causes the ocean plate to go under the continental plate and pull the land and water down, forming a trench.
What feature forms when an oceanic plate collides with a continental plate?
When an ocean plate collides with a continental plate, a subduction zone occurs and forms a deep trench. An ocean plate is more dense while a continental plate is less dense which causes the ocean plate to go under the continental plate and pull the land and water down, forming a trench.

The plate boundary is continental - continental. This creates mountains and earthquakes, but one plate doesn't go under the other
When an oceanic plate collides with a continental plate the oceanic plate is usually subducted because?
the oceanic plate is denser than the continental plate due to its composition and temperature. This causes the oceanic plate to be forced beneath the continental plate in a process known as subduction.
What is it called when the earths plate go under the ocean and spread out?
it creates a tsunami
When an oceanic plate collides with the continental plate the oceanic plate is usually subduction because?
with all that water pushing down on the plate, one of the plates has to go under. the one that is sliding under the top plate is usually the one that goes under. <3 hope this helps:)
Why does the oceanic crust go under the continental crust when they collide?
Oceanic crust is denser than continental crust because it is composed of mafic rocks like basalt, whereas continental crust is made of felsic rocks like granite. This density difference causes the oceanic crust to subduct under the less dense continental crust when they collide at convergent plate boundaries.
What order does the ocean floors go in?
The order is continental shelf, continental slope, continental rise, seamount, abyssal plain, mid ocean ridge, and trench
How does subduction works?
Subduction occurs when one tectonic plate slides beneath another, typically in a convergent boundary where plates are colliding. The descending plate is denser and cooler than the overriding plate, causing it to sink into the mantle. This process can lead to the formation of deep ocean trenches, volcanic arcs, and earthquakes.
When two plates collide what determines which plate comes out on top?
The density of the plates and the angle of the collision can determine which plate comes out on top when two plates collide. The denser plate tends to sink beneath the less dense plate, while the angle of collision can influence the direction of movement. Additionally, the presence of features like oceanic crust and continental crust can also impact which plate is subducted.
