The collision of plates commonly includes "subduction", where one plate is forced under the other, down into the mantle. These plates are melted and rise again, adding to the magma under the overlying plate. This creates heated rock that can later emerge through the surface in volcanoes.
Oceanic plates are thinner and denser than continental plates, so are the ones forced down, either under a continental plate or another oceanic plate.
What else can I help you with?
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.
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.
Why do earthquakes and volcanic eruptions occur in the ring of fire?
The volcanic eruptions are the cause of tectonic movement of the "plates" meaning that when the plates hit each other they cause the magma under the earth to rise and sometimes erupt causing ash and sometimes lava to leave the volcanic shell in an eruption
When a oceanic plate digs into earth's hot interior what occurs?
When an oceanic plate subducts into the Earth's hot interior, it sinks beneath a continental or another oceanic plate, leading to the formation of a trench. As the plate descends, it heats up and releases water and other volatiles, which can trigger melting in the overlying mantle. This process often results in volcanic activity and the creation of magma, contributing to the formation of volcanic arcs. Additionally, this subduction can lead to earthquakes due to the intense pressure and friction between the plates.
Where do earthquakes and volcanos occur?
Volcanoes tend to form at convergent tectonic plate boundaries where subduction is occurring (such as the western coast of South America) and at divergent plate boundaries where two tectonic plates are moving apart (e.g. the Mid-Atlantic-Ridge and Iceland). Earthquakes also occur at convergent boundaries and in fact these tend to cause the strongest earthquakes. Earthquakes also occur at transform boundaries (such as the San Andreas fault) however these do not tend to cause the formation of volcanoes. So to find volcanoes and large earthquakes you should be looking at convergent plate boundaries where subduction is occurring.
When ocean plates collide with continental plates what does the denser plate do?
sinks
When oceans plates collide with continental plates the denser ocean plate does what?
sinks
When ocean plates collide with continental plates the denser oceanic plate?
sinks
When plates collide the denser plate will ride over the less denser plate?
No, the denser plate sinks under the less dense plate in a process called subduction.
What does it mean when plates have subduction on each other?
When plates have subduction, it means that one tectonic plate is being forced beneath another plate. This process happens at convergent plate boundaries where two plates collide, and the denser plate sinks into the mantle. Subduction can lead to the formation of deep ocean trenches, volcanic arcs, and earthquakes.

What type of boundary is made when plates collide?
A convergent boundary is formed when plates collide. At this type of boundary, the denser plate sinks beneath the less dense plate in a process known as subduction. This collision often results in the formation of mountain ranges, volcanoes, and deep ocean trenches.
What occurs when two plates collide and one of the plates dips below the other?
It is called subduction. When subduction occurs one plate slips beneath the other and sinks into the Earth's mantle and creates a trench.
When ocean plates collide with continental plates the denser ocean plate?
is forced below the less dense continental plate in a process called subduction. This can lead to the formation of deep ocean trenches, volcanic arcs, and earthquakes along the subduction zone.
What happens when a tectonic plate slides under another tectonic plate?
This happens at a plate boundary. The oceanic plate subducts (sinks) under the continental plate, because it is heavier. (the oceanic plate is made of basalt and the continental plate is made of granite.) This happens at a destructive plate margin. it is called this because part if the oceanic plate is destroyed, because it melts as it sinks.
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.
What is the effect of a convergant boundary?
When convergent plates collide one is pushed beneath the other plate and sinks into the Earth's mantle. This process is known as subduction. Subduction creates trenches in the ocean, which is why trenches and associated with convergent plates.
