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.

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.
The type of boundary where two plates slide horizontally past each other?
oceanic/contintal
Why is the asthenosphere important to plate tectonics?
The crust slides around on this layer. (Continental+Oceanic drift) It helps the theory of tectonic plates because continental drift is where the continents were one big island call Pangaea but we slid apart.
Why does oceanic crust slide below continental crust in subduction zones?
The rock density, tectonic plate movement and gravity!!
How is the difference in density between the oceanic crust and the continental crust important?
Oceanic crust is thin, dense and composed of mainly silicon and magnessium While the Continental crust is thicker but less dense in comparism with the oceanic crust and its composed mainly of silicon and aluminium.
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).
What types of mountains form when oceanic plates collide and slide under continental plates?
A Ocean-To-Continent Collision. A Volcanic Mountain Will Form.
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.
What is formed when one tectonic plate slide under another tectonic plate?
Depends on the type of tectonic plate. If it is two continental plates, usually a mountain range will be formed and the plates will 'lock' together due to their thickness. The Indian sub-continent colliding with the eurasian plate is one example. If an oceanic plate is subducting under a continental plate an island arc can be formed or mountain range such as Japan and the Andies mountains respectively. This type is also where volcanoes will be commonly found unlike the collision of two continental plates, due to the magma formed from the subduction of the oceanic plate. If two oceanic plates collide, usually form an oceanic mountain range and lock together similar to the continental plates.
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 happens when a tectonic plate carrying oceanic crust collides with a tectonic plate carrying continental crust?
If the plates are moving at each other from directly opposite directions, the denser oceanic crust will subduct, or slide under the less dense continental crust, eventually melting back into the mantle. The hot gasses and pressure created by the melting process will seek release in the form of a volcano! :D
What are the differences between the three types of plate boundaries?
divergent, transform and convergent divergent plate boundaries move away from each other, convergent plate boundaries move toward each other, and transform plate bounties slide past each other.
How do transform boundaries form?
a transform boundary is:where 2 plates slide past each other,happens at continental vs. oceanic platesmost famous example: The San Andreas Fault Line
The type of boundary where two plates slide horizontally past each other?
oceanic/contintal
When one continental plate slides under another one is formed?
NO that would mean we are making heaps of tetonic plates although this scenario can cause an earthquake and for rocks to slide under or above the plates and the mantle
What is the process called when the oceanic plates slide down the slope of lithosphere-asthenospher boundary?
Ridge Push.
