The oceanic crust is formed at mid Atlantic ridge.A chain of under water mountain range with active volcanic activities pushes apart the new ocenic crust.Note that if ocean floor is created then it is also consumed else where at a subduction zone situated in Pacific Ocean so called ring of fire.Otherwise the volume of earth would go on increasing.
What else can I help you with?
What kind of plate boundary does a plateau form on?
A plateau can form on a convergent plate boundary where two plates collide, causing uplift and compression of the crust. It can also form on a divergent plate boundary where two plates move apart, leading to the stretching and thinning of the crust, creating a high, flat landform.
At what kind of boundary does oceanic lithosphere plunge beneath and overriding continental plate?
Oceanic lithosphere plunges beneath an overriding continental plate at a convergent boundary, specifically at a subduction zone. The denser oceanic plate is forced beneath the less dense continental plate due to tectonic forces, leading to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.
What kind of plate boundary has the most explosive volcanoes?
Convergent with the oceanic plate subducting under the continental plate.
What kind of boundary does oceanic lithosphere plunge beneath an overriding continental plate?
When oceanic lithosphere plunges beneath an overriding continental plate, it occurs at a convergent boundary, specifically a subduction zone. This process leads to the formation of features such as deep ocean trenches and volcanic arcs on the continental side. The denser oceanic plate is forced down into the mantle, which can trigger earthquakes and contribute to the geological activity of the region. Subduction zones are key areas for understanding plate tectonics and the recycling of Earth's crust.
What kind of rocks make up continental crust and oceanic crust?
Continental crust is mainly composed of granitic rocks such as granite and rhyolite, which are light in color and less dense. Oceanic crust is primarily composed of basaltic rocks, specifically basalt, which are dark in color and more dense than granitic rocks.
What kind of plate boundary cost old and heavy crust to sink in to the mantle?
A subduction zone is the plate boundary where old and heavy oceanic crust sinks into the mantle. At subduction zones, oceanic crust is forced beneath another tectonic plate, typically a continental plate, due to differences in density. This process can lead to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.
What kind of boundary is located at the mid ocean ridge?
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust.
What kind of crust is found under the ocean?
oceanic crust
What kind of crust usually goes into the mantle?
Oceanic crust gets subducted into the mantle.
What is the plate with oceanic crust sinking under one another plate with oceanic crust?
When one plate sinks under the other, it is callled subduction, no matter what kind of plate it is. When two oceanic plates collide, they form trenches(i.e. the mariana trench). Hope this answers your question!!!
What kind of plate boundary does a plateau form on?
A plateau can form on a convergent plate boundary where two plates collide, causing uplift and compression of the crust. It can also form on a divergent plate boundary where two plates move apart, leading to the stretching and thinning of the crust, creating a high, flat landform.
What kind of crust are Plates made of?
rocky almost cement crust like granite found in continental crust and basalt found in oceanic crust
Pulling forces form what kind of mountains?
I believe that this question has to do with earth science. When two continental plates come together, a convergent plate boundary, mountains form. If an oceanic plate and a continental plate converge, or come together, a subduction zone is form and the oceanic plate subducts under the continental usually because the oceanic plate is less dense. Hope I kind of answered the question..?
At what kind of boundary does oceanic lithosphere plunge beneath and overriding continental plate?
Oceanic lithosphere plunges beneath an overriding continental plate at a convergent boundary, specifically at a subduction zone. The denser oceanic plate is forced beneath the less dense continental plate due to tectonic forces, leading to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.
What kind of plate boundary causes mountains to form?
The plate boundary that causes mountains to form is called a convergent boundary.
What kind of plate boundary has the most explosive volcanoes?
Convergent with the oceanic plate subducting under the continental plate.
What are two kind of crust that a tectonic plate may contain?
Tectonic plates can have either continental crust, which is thicker and less dense, or oceanic crust, which is thinner and more dense. The type of crust influences the movement and behavior of the tectonic plates at plate boundaries.
