What is an example of an oceanic continental boundary?
One example of this type of oceanic-continental convergent boundary is the Andes mountain range of western South America. A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. …
What is continental continental convergent boundary?
Continent-Continent Convergence Another type of convergent plate boundary is when two continental plates collide. When two plates of continental crust collide, the material pushes upward. This forms a high mountain range. The remnants of subducted oceanic crust remain beneath the continental convergence zone.
What does a convergent boundary between oceanic and continental plate form?
Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent; sometimes an ocean trench immediately off shore of the continent; a line of volcanic eruptions a few hundred miles inland from …
What happens at an oceanic oceanic convergent boundary?
An ocean-ocean convergent boundary occurs location where two oceanic plates come together and the denser plate sinks, or subducts, beneath the less dense plate, forming a deep ocean trench. Chains of volcanoes, called island arcs, form over subduction zone melting occurs where the subducting plate reenters the mantle.
What 3 things are created by Convergent boundaries of oceanic and oceanic crust?
Oceanic/Oceanic Convergent Boundaries Such a convergent boundary includes a seafloor trench marking the earthquake-rattled subduction zone as well as an island arc: a line of volcanoes created by rock-melt in the mantle associated with subduction.
What geological events are possible with the oceanic oceanic convergence?
When oceanic- oceanic convergence take place, big events like volcanic activities, earthquakes, trenches and valleys forms. Some examples of oceanic convergence are the Aleutian islands, the Mariana’s islands.
How are oceanic oceanic and Oceanic Continental convergent boundaries different?
The oceanic plate is pushed under the continental plate and melted. Continental plates are much thicker that Oceanic plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates.
How are oceanic oceanic and Oceanic Continental convergent boundaries similar?
a. Oceanic-oceanic convergence occurs deep in the ocean where one oceanic plate is overlapped on top of another oceanic plate causing the formation of trenches. Oceanic-continental convergence triggers the formation of mountains, when a continental plate overlaps an oceanic plate on collision.
When the oceanic and continental Lithospheres collide?
When oceanic lithosphere and continental lithosphere collide, the dense oceanic lithosphere subducts beneath the less dense continental lithosphere. An accretionary wedge forms on the continental crust as deep-sea sediments and oceanic crust are scraped from the oceanic plate.
Which is formed when an oceanic plate converges with another oceanic plate?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.
When an oceanic and a continental plate converge?
When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Convergent boundaries are commonly associated with larger earthquakes and higher volcanic activity.
