What is the difference between the thickness of the continetal crust and oceanic crust?
In technical terms, the oceanic crust is denser than the continental crust so when the continental crust and the oceanic crust meet the continental crust will sink under and the oceanic crust will slide over and a volcano will be formed as well as producing earthquakes in the process.
Why does one continental plate slide under the other?
Because magma rises through hot spots( holes in the ground on the ocean floor) and cools forming new crust which repeats over hundreds of years making the oceanic crust more dense than continental crust. Since the oceanic crust is more dense, it sinks faster causing it to slide under the continental crust
What type of boundary forms when an oceanic plate is pushed under a continental plate?
a convergent boundary. The oceanic plate is then subducted under the continental plate because it is denser. This subduction creates earthquakes and volcanoes
What kind of plate boundary does subduction take place at?
A convergent plate boundary. a piece of continental crust and a piece of oceanic crust meeting at a convergent boundary.
Why is there no volcanoes at conservative margins?
As there is no subduction, the magma is not disturbed and the two plates simply slide past each other, crust is neither created, nor destroyed
Why does oceanic crust slide below continental crust in subduction zones?
The rock density, tectonic plate movement and gravity!!
Why does oceanic crust slide under continental crust during subduction?
The oceanic crust slides under the continental crust due to the differences in their densities. The continental crust is more felsic (contains more silica) which makes it lighter than the oceanic crust which is more mafic (containes more fe and mg). Because the process of subduction is very slow, gravitational forces have a stronger effect on the more dense oceanic crust, causing this crust to be pulled under the continental crust and down into the mantle.
Why does the oceanic crust slide beneath the continental crust at a subduction zone?
This is because the land mass is more buoyant, or lighter, than the oceanfloor.
What happens when a plate of oceanic crust collides with a plate of the continental crust and why does this happen?
The oceanic crust will slide under the continental crust. And the reason is because the oceanic crust is much denser and the continental crust is least dense.

Aera where an oceanic plate goes down into the mantle?
A subduction zone at a convergent plate boundary. Undersea trenches are formed where the oceanic plate subducts, and volcanism and earthquakes may result from the partial melting and downward movement of the subducting crust.
These are formed when oceanic plates slide under continental plates?
When oceanic plates slide under continental plates they form subduction zones. Subduction zones always occur at convergent boundaries where one plate slides beneath another plate.
Where does subduction most often occur?
Subduction only occurs on convergent plate boundaries, which means that the two plates are colliding. Subduction is basically the sinking of one plate below another. This happens when an oceanic plate and a continental plate collide, and the more dense oceanic plate filled with more mafic rock types (with magnesium/iron and less silica) slide under the less dense continental crust.
What is the difference between continentalcrust and the oceanic?
Continental crust is thicker and less dense while oceanic crust is thinner and more dense, so essentially continental crust takes a higher position than oceanic crust. When oceanic and continental plates collide, oceanic plates slide underneath continental plates(if this makes what I said any clearer).
Why does one continental plate slide under the other?
Because magma rises through hot spots( holes in the ground on the ocean floor) and cools forming new crust which repeats over hundreds of years making the oceanic crust more dense than continental crust. Since the oceanic crust is more dense, it sinks faster causing it to slide under the continental crust

How the Earth's crust remains the same size?
The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another.
