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.

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
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.
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?
The tip of the continental shelf (which has a gentle slope) where if you go any farther, the continental slope forms, which has a very steep slope.
What type of landforms do you get along a continental continental convergent boundary?
Two things can happen, first the plates can collide into each other forcing one plate to go under the other. The second is that these plates can crumble up causing mountains to form.
What feature is formed when an ocean 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.

What is it called when the earths plate go under the ocean and spread out?
it creates a tsunami
How does subduction works?
Subduction occurs when a denser heavier plate is forced under a lighter plate. It is usually the oceanic plate that sub ducts under a continental plate and the are marked by deep ocean trenches
When two plates collide what determines which plate 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.
When an oceanic plate collides with a continental plate the oceanic plate is usually subducted 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?
because the ocean base is hevier than the other crust

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.
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
