If you are talking about plate tectonics, the action you're referring to is called subduction.

Where is the oceanic crust sinking into mantle?
Usually when it meets another tectonic plate at a convergent plate boundary. If the oceanic plate converges with a continental plate the denser oceanic plate will be forced under the continental plate. If it converges with another oceanic plate the older (and therefore cooler and denser) plate will be forced under the younger plate.
What is slabpull?
Slab Pull Force occurs when a denser oceanic plate is forced beneath a less dense continental plate or oceanic plate in a process called subduction. It's the force caused by suction of the cold dense lithosphere into the asthenosphere at destructive margins. Basically, because lithosphere is denser than asthenosphere, there is gravitational imbalance which is passed on to the crust. this causes the lithosphere to be sucked inwards at the oceanic trenches into deep asthenosphere.
Why do you think the denser plate subducts in a collision?
because the denser plate is always the one that sinks
How does subduction occur?
A plate will subduct for tens to hundreds of millions of years.
The location where the sinking of one plate beneath the other in a collisional boundary occurs is called a?
It is called a subduction zone.
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.
Why did chances peak erupt?
The volcano erupted due to it lying on a destructive plate boundary, where the denser North American Plate, was sinking underneath the less dense Caribbean Plate causing a subduction zone. Due to the sinking of the North American Plate into the mantle, magma started to rise to which caused the volcano to erupt.
When a more dense oceanic plate sinks under continental plate?
This is called a destructive plate boundary. It occurs due to the fact that the oceanic crust is far denser than the continental crust. As a result it subducts into the mantle and is incenerated. Hope it helped:)
When a more dense plate slides beneath a less dense plate?
If two plates of different densities collide, the more dense one is forced downwards and eventually becomes part of the mantle. This is usually an oceanic plate. The less dense, continental, plate is pushed up and mountains form along the edge.
What plate always subducts?
The heavier/denser oceanic plate subducts the lighter, less - dense continental plate.
How subsidence occur?
Subsidence occurs when one plate is denser than the plate it is moving into. It then slips under the less dense plate and melts into the mantle.
Where is the oceanic crust sinking into mantle?

What type of plate boundary is when one sinks beneath another?
A convergent plate boundary is where one of the plates is sinking beneath another, and the other one is being pushed on top of the subducting plate. This is called a subduction zone. This happens when denser, heavier oceanic crust meets less dense, thicker, continental crust.When two plates converge, and one is less dense, that plate goes under the more dense plate into the mantle, this is called subduction.subduction will happen and a volcano will be formed. when one plate slides beneath another one magma from earths mantle is being pushed up on earths surface.
What is the location where sinking of a plate occurs is called?
squat-thrust
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 occurs when dense oceanic plates collide with continental plate?
The oceanic plate subducts under the continental because it is denser. The Andes are being formed in this way and the Himalayas started that way also.
