How is oceanic crust forced back into the earth’s mantle? It wants to float but is forced to curl as it cools. It wants to float but is forced under by colliding plates.Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.As the oceanic plate descends into the mantle some of it melts. This material moves into the mantle above the plate and causes the mantle to melt. This liquid rock, called magma, rises to the surface because it is less dense then the surrounding rock. If the magma reaches the surface of the Earth, a volcano forms.

Where does oceanic crust go back into the mantle?
Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.
What happens to the oceanic plate as it pushes into the mantle?
As the oceanic plate descends into the mantle some of it melts. This material moves into the mantle above the plate and causes the mantle to melt. This liquid rock, called magma, rises to the surface because it is less dense then the surrounding rock. If the magma reaches the surface of the Earth, a volcano forms.

What pushes the tectonic plate back into the mantle?
Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle.
Does conduction allow oceanic crust to sink back into the mantle?
At deep-ocean trenches, conduction allows oceanic crust to sink back into the mantle. Is the following statement true or false? The Pacific Ocean is shrinking. Why is the Atlantic Ocean expanding?
Does oceanic crust melt in the mantle?
At depths of 100-250 km the oceanic crust begins to melt. The resulting magma, along with the water mentioned earlier, rises up into the wedge of mantle above. This rising material then lowers the melting point of the hot mantle wedge, so in turn parts of that melt.
What happens to oceanic crust as it collides with continental crust Why?
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.
What happens when oceanic plates collide?
When two oceanic plates converge, the cooler, denser one descends, or subducts, beneath the overriding plate and sinks into the mantle. When an oceanic plate meets a plate with a continent riding atop it, the oceanic plate is again subducted.

Seafloor Spreading | National Geographic Society
Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth’s lithosphere—split apart from each other.

Continental Movement by Plate Tectonics – University of …
Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents.

When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at …
When oceanic and continental plates collide What is the result?
When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction. A deep ocean trench forms at this subduction boundary.
What is formed when the oceanic plate collide?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.
Is drag force a driving force of tectonic plates?
The drag on the base of the oceanic lithosphere can both drive or resist plate motion, depending on the relative motion between the plate and the underlying mantle.
What is the basic driving force for plate movement?
The gravity-controlled sinking of a cold, denser oceanic slab into the subduction zone, dragging the rest of the plate along with it, is considered to be the driving force of plate tectonics. Forces deep within the Earth’s interior drive plate motion.
What causes ridge push to occur?
plate tectonics
(the Mid-Atlantic Ridge), known as ridge push, in the Atlantic Ocean. This push is caused by gravitational force, and it exists because the ridge occurs at a higher elevation than the rest of the ocean floor.

How does convection transfer heat into mantle?
The mantle is heated from below (the core), and in areas that are hotter it rises upwards (it is buoyant), whereas in areas that are cooler it sink down. This results in convection cells in the mantle, and produces horizontal motion of mantle material close to the Earth surface.
What is the process of heat transfer in the Earth’s mantle?
The main heat transfer mechanism in the Earth’s mantle is convection, a thermally driven process where heating at depth causes material to expand and become less dense, causing it to rise while being replaced by complimentary cool material that sinks.
Why does the oceanic crust sink beneath the continental crust at the subduction zone?
Because ocean crust is more dense than continental crust, it will sink beneath continents if tectonic forces push the oceanic crust into the continent.
Why does subducting oceanic crust melt into magma?
As the ocean crust sinks deeper into the mantle the pressure increases (the temperature of the ocean crust rocks increases more slowly because rocks are poor conductors of heat). At depths of around 100 km beneath the surface, the pressure is great enough for the hydrous minerals to undergo metamorphism.
Where is oceanic crust destroyed?
Just as oceanic crust is formed at mid-ocean ridges, it is destroyed in subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary.
What forms when one oceanic plate is forced beneath another plate?
When one oceanic plate is forced beneath another plate, a subduction zone is formed.
When oceanic crust and continental crust collide what features are created?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.
What happens when oceanic crust collides with continental crust at a plate boundary quizlet?
What happens when oceanic crust collides with continental crust? Subduction occurs as the denser oceanic plate sinks beneath the less dense continental plate. What happens when two plates carrying contintental crust collide? Neither plate subducts instead the collision squeezes the crust into mountain ranges.
When an oceanic crust and continental crust plate meet which of the following is the most likely to happen?
Near the boundary the earthquakes are near the surface. Further from the boundary the earthquakes are progressively deeper in the earth. So at the converging boundary of an oceanic tectonic plate and a continental tectonic plate, the oceanic plate is subducted resulting in mountain building, volcanos and earthquakes.
What can happen when two oceanic plates converge and one is subducted into the mantle?
When two oceanic plates collide one oceanic plate is eventually subducted under the other. Where one plate slides under the other is referred to as the ‘subduction zone’. As the subducting plate descends into the mantle where it is being gradually heated a benioff zone is formed.

What does oceanic oceanic form?
Oceanic/Oceanic Convergent Boundaries
Such a convergent boundary includes a seafloor trench marking the earthquake-rattled subduction zone as well as an island arc: a line of volcanoes created by rock-melt in the mantle associated with subduction.
What force caused the movement of the continents?
1 Answer. The theory of plate tectonics suggests that it is convection currents in the mantle of the earth that causes the movement of the continental plates.
