What is oceanic continental convergence?

Ocean-Continent Convergence. When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The subducting plate causes melting in the mantle above the plate.

What is the definition of continental continental convergence?

Continent-Continent Convergence Another type of convergent plate boundary is when two continental plates collide. Continental lithosphere is low in density and very thick. When two plates of continental crust collide, the material pushes upward. This forms a high mountain range.

What are oceanic and continental plates?

Oceanic plates are formed by divergent plate boundaries. Continental plates, meanwhile, are formed primarily by convergent plate boundaries. These zones represent areas where oceanic plates collide with and plunge underneath continental plates – a process called subduction.

What happens when oceanic and oceanic converge?

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 meaning of oceanic oceanic?

(oʊʃiænɪk ) adjective [ADJECTIVE noun] Oceanic means belonging or relating to an ocean or to the sea.

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.

Where is the oceanic plate?

mid ocean ridges
oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates.

What are oceanic plates?

Oceanic plates are formed by divergent plate boundaries. These zones, located along mid-ocean ridges, represent areas where upwelling magma creates new oceanic crust. As oceanic plates subduct, they melt to form magma. This magma cools over millions of years, producing intrusive igneous rock and new continental crust.

What do oceanic and continental plates form?

When oceanic crust converges with continental crust, the denser oceanic plate plunges beneath the continental plate. This process, called subduction, occurs at the oceanic trenches. The subducting plate causes melting in the mantle above the plate. The magma rises and erupts, creating volcanoes.

What is the meaning of oceanic plate?

What is oceanic boundary?

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 is an example of a continental – oceanic convergent boundary?

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 are the main difference between the Oceanic and continental plates?

Oceanic plates are much thinner than the continental plates. When an oceanic plate meets a continental plate at a convergent boundary the oceanic plate is forced under the continental plate and destroyed. The convergent boundaries between ocean and continental plates create subduction zones.

What is ocean continent convergence?

Continent – Ocean Convergence Or The Cordilleran Convergence Continent – Ocean Convergence is also called Cordilleran Convergence because this kind of convergence gives rise to extensive mountain systems. A cordillera is an extensive chain of mountains or mountain ranges. Continent – Ocean Convergence is similar to ocean – ocean convergence.

Which tectonic plates are oceanic?

Oceanic plates are tectonic plates that are at the bottom of the oceans. They are thinner than continental plates, and they are also more dense, so they ride lower on the mantle. They are more dense because they are mostly basalt, having been erupted from mid-ocean ridges.
