What is a result of a continental crust and oceanic crust collision?

Oceanic crust is formed primarily of basalts (density= 3.3 g/cm^3) and is therefore denser than that of continental crust, which is composed mainly of granite (density= 2.7 g/cm^3). This will result in a subduction zone, where the oceanic crust will be subducted underneath the continental crust and be recycled into the asthenosphere. At these locations its typically to see deep trenches and volcanic arcs.

∙ 12y agoWhere oceanic lithospheric plates converge or collide, the older, denser, and colder oceanic plate will move underneath the less dense oceanic plate. This is called subduction. The subducting oceanic plate will basically flow slowly downward at an angle as a slab of rock until heating from friction and the geothermal gradient, along with the presence of water that is trapped in the rock, causes it to melt. The melting occurs in the asthenosphere. The melted rock then rises, due to buoyancy, through the rock occupying the space above it in processes taking tens to hundreds of thousands of years. Eventually, some of the molten rock may penetrate the oceanic crustal seafloor above it, resulting in undersea volcanoes. If these eruptions continue long enough, the volcano will eventually breach the surface of the ocean sea level and form island arcs, which form a line along the subduction zone.

What forms from collision of continental crust and oceanic crust?
A basic mountain should be formed from the collision of continental crust and oceanic crustAnswerWhen an oceanic and a continental crust collide, the heavier oceanic crust tends to subduct under the lighter continental crust. Because of the collision and corresponding compression and also because of volcanism related to dehydration and melting of the subducted plate a mountain range is formed. The Andes mountain range is a, if not the, most typical example.
How are convergent plate margins characterized?
Convergent plate margins are characterized as collision zones between plates and may involve continental to continental crust, continental to oceanic crust, or oceanic to oceanic crust. Those that involve oceanic crust result in subduction of the more dense plate into the Earth's mantle. Continental to continental plate collisions result in uplift of the surface features and mountain building and the margin may eventually become welded together.
What would be expected to result from a collision between a continental lithospheric plate and a oceanic lithospheric plate?
Typically the less dense continental plate would stay afloat while the denser oceanic plate would be submerged below. This can result in volcanic eruptions at the subduction zone due to oceanic crust undergoing increased pressure and temperatures as it descends below the continental crust.
Where does the oceanic crust begin?
The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
Oceanic crust is what than continental crust?
Oceanic crust is thinner and denser than continental crust.

Where is the crust deepest?
Deepest doesn't really make sense, so I'm going to answer assuming you meant thickest. Oceanic crust or continental crust? Oceanic crust is thickest at spreading centers and continental crust is deepest at collision zones, the Himalayan/Tibet collision zone to be exact.
Why does ocean crust dive below continental crust?
The ocean crust dives below the continental crust due to a collision. This collision involves the two types of crust and since the oceanic crust is denser, it sinks to the bottom while the less dense continental crust rises to the top.

Typically the less dense continental plate would stay afloat while the denser oceanic plate would be submerged below. This can result in volcanic eruptions at the subduction zone due to oceanic crust undergoing increased pressure and temperatures as it descends below the continental crust.
What two types of crust result you subduction?
oceanic and continental
What is the outcome of the collision between oceanic and continental crust?
Usually subduction of the denser thinner oceanic crust under the lighter thicker continental crust. This also produces a row of volcanoes in the continental crust producing lava high in water content and resulting in explosive eruptions.
Where does the oceanic crust begin?
The continental shelf is normally made out of continental crust, the oceanic crust begins at the base of the continental rise. However in most places the oceanic crust near the continental margins is covered by continental sediments (eroded form the continents) carried down onto the Oceanic planes by deep sea canyons running off the continental rises.
What is the process of a oceanic plate colliding with a continental plate?
Its when the oceanic crust and the continental crsut colide together.
Oceanic crust is lighter than the continental crust?
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
What is the difference between the continental crust and the oceanic crusts?
Most significantly, there is a material difference in the weight and density of the two types of crust. This manifests itself when tectonic movement brings oceanic in continental plates into collision. Oceanic crust is relatively denser but typically about 100km this. Continental crust is lighter but almost twice as thick--about 200km.
Is the continental crust thinner than the oceanic crust?
It is not. The oceanic crust is thinner than the continental crust!
