When an oceanic plate collides with a continental plate is the oceanic plate forced down into the mantle?

An earthquake is made. Shock waves move in all directions from that place ( which is called the focus) and then it reaches the ground. This point is called the epicenter. The earth then starts violently shaking.

Does subduction create or destroy oceanic crust?
In a subduction zone the crust is forced inot the mantle where it is eventually melted and destroyed
What is the rigid part of the tectonic plates that is made up of oceanic crust or continental crust and the upper mantle?
the lithoseshere
What happens when plates collide and one plate sinks?
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.
Why can continental crust displace more of the mantle than oceanic crust can?
the mantle is a hot ocean of lava basically and on it floats a series of tectonic plates, on the surface of the plates is the crust. there is your answer hope it helps.
How does the earths mantle differ from its crust?
Inner core: 2450 km thick Outer core: 2300 km thick Lower mantle: 2500 km thick Upper Mantle: 400 km thick continental crust: 30-70 km thick Oceanic Crust: 6 km thick
What does the phrase 'the less buoyant plate is subducted' mean?
This means that the cooler, heavier oceanic plate at an oceanic to oceanic convergent boundary is forced into the mantle - under the hotter, lighter oceanic plate. OR At oceanic to continental boundary the heavier oceanic plate is forced into the mantle under the lighter continental plate.
Why does oceanic lithosphere sub duct while continental lithosphere does not?
Oceanic lithosphere is dense enough to be forced down into the mantle. Continental lithosphere is not.
What happens when continental collides with continental crust?
The oceanic crust is force down into the mantle in a process called subduction. The subducting oceanic plate will introduce water into the hot mantle, causing some of the rock to melt. The molten rock will rise through the overriding continental crust to form volcanoes.
What is the motion of plates in a subduction zone?
In a subduction zone, the dense, cold oceanic plate collides with the lighter, warmer continental plate and is forced down underneath it into the mantle. The motion is downwards and the force is called "slab pull".
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
Where oceanic crust collides with continental crust is the?
This type of plate boundary is a convergent boundary where subduction of the denser oceanic slab into the mantle will occur. Because of this it may also be called a destructive margin.
A seafloor plate collides with a continal plate.what will happen?
The oceanic plate (sea-floor plate) is denser than the continental plate, so the oceanic plate will be pulled under the continental plate (subduction) and into the upper mantle, creating an underwater volcano.
When does a part of oceanic plate sink into the 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.
Does the continental or the oceanic crust extend farther into the mantle?
The continental crust because it is thicker than the oceanic crust
What happens when a plate of oceanic crust collides with a plate of Continetal crust why?
the oceanic crust slides down and burns in the mantle and forms a volcano
Where is old seafloor destroyed?
Oceanic crust isn't destroyed because it's old; it is, in fact, destroyed due to destructive plate boundaries. This is where a continental plate and an oceanic plate move towards each other. As the oceanic crust is denser, it is pushed under the continental plate. Here it is forced into the mantle of the earth, where it is destroyed due to heat and convection currents.
What are the most common convergent boundaries?
Convergent plates are two tectonic plates that are colliding as they move toward each other. There are several types of converging plate boundaries.Oceanic to oceanic plate convergence:Where an oceanic plate collides with another oceanic plate, the more dense plate subducts into the mantle. The subduction results in the partial melting of lithospheric rock above the area of the subduction, causing underwater volcanoes to form. If the volcanoes grow to reach the surface, volcanic arc islands are formed. Oceanic to continental plate convergence:Where an oceanic plate collides with a continental plate, the oceanic plate is subducted due to the fact that it is more dense, which can also cause volcanism and mountain building. Continental to continental plate convergence:Where two continental plates collide, neither subducts into the mantle, the crust is thickened, and mountain ranges are formed from the thickening and uplift.
