It gets pushed down under the lighter plate. This process is called subduction.

How does density affect how plates interact?
Density plays a key role in convergent boundaries. When two plates collide at a convergent plate boundary, it is the denser plate that will subduct.
Why do oceanic plates move under continental plates when the two collide?
Oceanic plates move under continental plates when they converge together because the oceanic plate is more denser than the continental plate.
Which two plates collide in the Appalachian mountains?
The pacific plate and the cocos plate
How does a ocean plate go under a continental plate?
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 land form is created by tectonic plates crashing together?
this depends on the two plates that collide. Ocean plates are much heavier than continental plates. If an ocean and continental plate collide, the ocean plate sinks underneath and creates a trench. If two ocean plates or two continental plate collide, it creates a mountain range/ oceanic ridge depending on the type.

Where does subdution occur?
Subduction (I believe that's what you meant) occurs at CONVERGENT boundaries, where two plates collide and the less dense one remains and the denser one sinks. An example of subduction is two oceanic plates colliding. Oceanic plates contain mainly basalt, which is dense. The oceanic plate closer to a heat source (hot spot, volcano) would remain in place while the denser plate sinks (cold water is denser than hot water so it sinks) below the other. When an oceanic plate and a continental plate collide, the oceanic plate sinks because granite (what continental plates are composed of mainly) is less dense than basalt, therefore the oceanic plate would sink. However, when two continental plates collide, because both plates are made of granite and are not very dense, they push and shape the land into mountains.
How do plate move a convergent boundary?
A convergent boundary is one where two plates are grinding into each other, so the plates are moving toward each other. If one plate more dense than the other, (say a continent and an oceanic plate collide) then the denser plate (the oceanic plate) may be subducted. If two plates of similar or the same density collide, then neither plate will subduct, and crustal thickening may occur. This is the process which formed the Himalayas, resulting from the pressure of two continental plates, the Indian and the Asian.

What happens if two plates collide at a destructive plate boundary?
an earthquake
What is the type of plate boundary where two plates collide?
Convergent Boundary.
What is the definition of colliding boundary?
these boundaries are formed when two plates collide. When the two plate bump one plate is absorbed in the mantle of the other. Heat and pressure when these plates collide causes volcanoes and earthquakes.
When two sections of earths crust collide what kind of boundary is this?
Destructive (Plate) Boundary.Under converging convection currents in the asthenosphere, two plates converge.This is called slab pull.The denser plate sinks, then subducts into the asthenosphere and melt into magma.
What is colliding boundary?
these boundaries are formed when two plates collide. When the two plate bump one plate is absorbed in the mantle of the other. Heat and pressure when these plates collide causes volcanoes and earthquakes.
