Oceanic Continental Convergent Boundary Example
Oceanic Continental Convergent Boundary Example. Here we have an example where the cocos plate, within 30 million years of being created, is being forced to subduct under the caribbean plate because the oceanic lithosphere is converging directly with continental lithosphere. Where tectonic plates converge, a plate capped by thin oceanic crust descends (subducts) beneath a plate with much thicker continental crust.

In convergence there are subtypes namely: Juan de luca ridge the first event had an earthquake with a magnitude of 9.2 and was around 1700's. Along a convergent boundary two lithospheric plates collide against each other.
An Example Of An Oceanic/Oceanic Convergent Boundary Is That Between The Pacific And Mariana Plates, Which Includes The Mariana Islands Arc And A Subduction Zone Encompassing The Mariana Trench,.
Often it is the older and colder plate that is denser and subducts beneath the younger and warmer plate. Where tectonic plates converge, a plate capped by thin oceanic crust descends (subducts) beneath a plate with much thicker continental crust. As both plates collide, the denser plate made of oceanic crust is subducted underneath the less dense plate.
This Process Is Called Forced Subduction.
•when two plates come towards each other they create a convergent plate boundary. Juan de luca ridge the first event had an earthquake with a magnitude of 9.2 and was around 1700's. When one of the plates is an oceanic plate, it gets embedded in the softer asthenosphere of the continental plate, and as a result, trenches are formed at the zone of subduction.
In Convergence There Are Subtypes Namely:
An example would be the convergence of the oceanic nazca plate colliding with the continental south american plate producing the andes mountain chain. Along a convergent boundary two lithospheric plates collide against each other. See answer (1) best answer.
Here We Have An Example Where The Cocos Plate, Within 30 Million Years Of Being Created, Is Being Forced To Subduct Under The Caribbean Plate Because The Oceanic Lithosphere Is Converging Directly With Continental Lithosphere.
This is the point where the north and south american plates are subducting underneath the caribbean plate. •dense oceanic crust will subduct beneath continental crust or a less dense slab of oceanic crust. Above is a cross section of the oceanic trench found at this convergent boundary.
The Second Event Was Another Earthquake With A Magnitude Of 8.7 Around 1820'S.
Here is an example of spontaneous subduction occurring off the coast of japan. •the plates can meet where both have oceanic crust or both have continental crust, or they can meet where one has oceanic and one has continental. At a convergent boundary between oceanic and continental lithosphere, the oceanic plate will always subduct, which will cause earthquakes and form volcanic arcs.
