Where is an example of an oceanic oceanic convergent boundary?
Oceanic/Oceanic Convergent Boundaries 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, the deepest part of the World Ocean..
What is oceanic plate margin?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
What do oceanic oceanic boundaries form?
Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
What happens when Oceanic and oceanic plates collide?
When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone. … Old, dense crust tends to be subducted back into the earth. An example of a subduction zone formed from a convergent boundary is the Chile-Peru trench.
What is the cause of oceanic Oceanic?
Continued subduction of the South American Plate brings sea water, locked in the ocean crust, deep into the mantle. … As the plate heats up the water is liberated, lowering the melting point of the mantle and causing partial melting.
What does Oceanic oceanic convergence create?
Oceanic – oceanic convergence This water reduces the melting temperature of rocks in the asthenosphere and causes partial melting. Partial melt will travel up through the asthenosphere, eventually, reach the surface, and form volcanic island arcs.
