Plate Tectonics Oceanic-continental convergent plate boundaries are very similar to oceanic-oceanic boundaries except that one plate is continental. Since oceanic crust has density of 3g/cc and continental crust has a density of only 2.7g/cc whenever oceanic crust collides with continental crust the oceanic crust subducts.

- Convergent boundaries that involve at least one oceanic plate form subduct … ion zones, where an oceanic plate plunges into the mantle. Volatiles carried into the mantle lower the melting point of the rock there, allowing magma to form. At divergent boundaries the crust becomes thinner. This reduces pressure on the upper mantle, thus lowering melting points and generating magma. Transform boundaries have no such means of producing magma.

Aleutian Islands Convergent Boundary - Aleutian Islands. The Aleutian Trench (or Aleutian Trough) is a subduction zone and oceanic trench which runs along the southern coastline of Alaska and the adjacent waters of northeastern Siberia off the coast of Kamchatka Peninsula. It is classified as a marginal trench in the east as it runs along the margin of the continent.

Plate tectonics The nature of a convergent boundary depends on the type of plates that are colliding. Where a dense oceanic plate collides with a less-dense continental plate, the oceanic plate is typically thrust underneath because of the greater buoyancy of the continental lithosphere, forming a subduction zone.

Tectonic Plates and Plate Boundaries Convergent margins. A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either continental or oceanic crust.

Earthquakes: tectonic plates 1 Where two plates converge at an oceanic trench a subduction boundary is formed as cold oceanic lithospheres are pushed back down into the mantle. 2  This happens because the oceanic plate is denser than the continental plate so, as they move together, the oceanic plate is forced underneath the continental plate.

Plate Boundaries: Convergent, Divergent, and Transform Boundaries A convergent boundary is a boundary where two separate plates are pushing into each other. There are two kinds of surface features that are associated with a convergent boundary. The first is a deep ocean trench that forms a line of the two colliding plates. One plate made of oceanic crust can slide down underneath another plate, forming this narrow, deep trench.

Convergent Boundary: Definition, Facts & Examples A convergent boundary (or destructive boundary) is where two plates are moving towards each other -- where they're colliding. The pressure and friction is great enough at these boundaries that the material in the Earth's mantle can melt, and both earthquakes and volcanoes happen nearby.

Convergent boundary Convergent boundary. In plate tectonics, a convergent boundary, also known as a destructive plate boundary, is a region of active deformation where two or more tectonic plates or fragments of the lithosphere near the end of their life cycle. This is in contrast to a constructive plate boundary (also known as a mid-ocean ridge or spreading center).

What happens at convergent boundaries? Convergent plates are two tectonic plates that are colliding as they move toward each other. There are several types of converging plate boundaries. Oceanic to oceanic pl…ate convergence: Where an oceanic plate collides with another oceanic plate, the more dense plate subducts into the mantle.

What is a convergent subduction boundary? A convergent boundary with no subduction is a continental-continental boundary. Because oceanic crust is denser than continental crust, it is always the subducting plate in a …oceanic-continental boundary. In an oceanic-oceanic boundary, one of the plates will subduct, depending on several factors.

- The location where two plates meet is called a plate boundary. Plate boundaries are commonly associated with geological events such as earthquakes and the creation of topographic features such as mountains, volcanoes, mid-ocean ridges, and oceanic trenches.here the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The lateral relative movement of the plates typically ranges from zero to 100 mm annually.

- Where the plates pull apart completely, magma fills the gap, forming new crust. New crust is forming along the mid-ocean ridge, a 70,000-kilometer-long (43,000-mile-long) volcanic mountain chain that runs through our deep oceans. The boundary where two plates collide is called a convergent margin. In some cases one plate slides under the other (a process called subduction). Deep earthquakes occur in these regions. Subduction causes melting deep below Earth's surface, and creates pools of magma.

Plate Tectonics Divergent Boundaries. Divergent boundaries occur anywhere two plates are separating from each other and new oceanic lithosphere is formed. As suggested by Hess, this is due to upwelling magma that causes the crust to bulge and, as a result, thin and fracture.ceanic-continental convergent plate boundaries are very similar to oceanic-oceanic boundaries except that one plate is continental. Since oceanic crust has density of 3g/cc and continental crust has a density of only 2.7g/cc whenever oceanic crust collides with continental crust the oceanic crust subducts.

Convergent Plate Boundaries Here the Nazca Plate is subducting beneath the South American plate. Visit the Interactive Plate Boundary Map to explore satellite images of convergent boundaries between oceanic and continental plates.hen a convergent boundary occurs between two oceanic plates one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle and at a depth of about 100 miles (150 km) the plate begins to melt.

Is Mariana's trench a oceanic-oceanic convergent boundary? As with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed. The Marianas Trench (paralleling the Mariana Islands), for example, marks where the fast-moving Pacific Plate converges against the slower moving Philippine Plate.s with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed.

Convergent boundary In a subduction zone, the subducting plate, which is normally a plate with oceanic crust, moves beneath the other plate, which can be made of either oceanic or continental crust. During collisions between two continental plates, large mountain ranges, such as the Himalayas are formed. Oceanic-continental.hen one plate is composed of oceanic lithosphere and the other is composed of continental lithosphere, the denser oceanic plate is subducted, often forming an orogenic belt and associated mountain range. This type of convergent boundary is similar to the Andes or the Cascade Range in North America.
