Tectonic Plates and Plate Boundaries 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.

- 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.ubduction processes in oceanic-oceanic plate convergence also result in the formation of volcanoes. Over millions of years, the erupted lava and volcanic debris pile up on the ocean floor until a submarine volcano rises above sea level to form an island volcano.

Types of Plate Boundaries Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust. This forms an active continental margin between the subduction zone and the edge of the continent. The leading edge of the continental plate is usually studded with steep andesitic mountain ranges.

Convergent Boundaries between Tectonic Plates In the case of a convergent boundary between two oceanic plates, 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.

- Descriptions[edit] 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.

- At convergent plate boundaries, sedimentary rock from the ocean floor gets pushed down into the mantle. The crust increases in temperature as it dives deeper into the mantle. Eventually, the crust melts and rises to the surface causing a volcanic eruption, creating igneous rocks.

- 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.

Convergent Boundary: Definition, Facts & Examples When one oceanic and one continental plate collides, the denser oceanic plate subducts beneath the continental plate. In this case, an underwater trench can form on the oceanic side, and volcanoes and mountains can form on the continental side. To unlock this lesson you must be a Study.com Member.he collision of this oceanic and continental plate was how the Andes mountains were formed. Convergent boundaries can also form islands. The northern part of the Pacific Plate is subducting under the North American Plate, and the result is the formation of the Aleutian Islands.

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater (Iceland is an exception) and form submarine mountain ranges called oceanic spreading ridges.

Mid-ocean ridge Mid-ocean ridges are geologically active, with new magma constantly emerging onto the ocean floor and into the crust at and near rifts along the ridge axes. The crystallized magma forms new crust of basalt (known as MORB for mid-ocean ridge basalt) and gabbro. They are formed by two oceanic plates moving away from each other. The rocks making up the crust below the seafloor are youngest along the axis of the ridge and age with increasing distance from that axis.

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. 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.

- When 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.he Himalaya Mountain Range is the best active example of this type of plate boundary. Visit the Interactive Plate Boundary Map to explore satellite images of the Himalaya Range where the Indian and Eurasian plates are currently in collision.

Convergent Boundary Colliding Plates Collision boundaries. Continental crusts that collide form a convergent boundary also. When two continental crusts collide a large mountain range forms between the two crusts. The Himalayan Mountains are the result of a continental collision between the Indo-Australian Plate and the Eurasian Plate.

- A convergent boundary is a place where two plates collide, which can form earthquakes from the impact, and volcanoes. Mountains can also be formed by this process.

Types of Geography Features at a Plate Boundary Trenches are geological features formed by convergent boundaries. When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone. This process results in the formation of a trench. The Marianas Trench is an example of a trench formed by the convergence of two oceanic plates.

- Convergent plate boundaries. 1  Oceanic-continental The denser oceanic slab slides under the continental slab. The contact region is called a subduction zone, and a trench is formed there. 2  Oceanic-oceanic One of the oceanic plates slides underneath the other. The region of contact is again called a subduction zone.

Mid-ocean ridge The buoyant melt rises as magma at a linear weakness in the oceanic crust, and emerges as lava, creating new crust upon cooling. A mid-ocean ridge demarcates the boundary between two tectonic plates, and consequently is termed a divergent plate boundary.ceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. There are two processes, ridge-push and slab pull, thought to be responsible for the spreading seen at mid-ocean ridges, and there is some uncertainty as to which is dominant.

Convergent Boundary Subduction zones. Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. The continental crust is lighter and less dense than oceanic crust. Continental crust's density is approximately 2.7 grams per cubic centimeter.Oceanic crust is thinner and the average density is about 3.3 cubic centimeters.When the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. convergent boundary forms when two continental plates collide. Neither plate subducts because the crusts have approximately the same density. Instead, the rocks are smashed together causing them to recrystallize due to the intense heat and pressure from the colliding plates.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. Thus at divergent boundaries, oceanic crust, made of basalt, is created. When two plates come together, it is known as a convergent boundary. The impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain range, and sometimes bends the other down into a deep seafloor trench. A chain of volcanoes often forms parallel to the boundary, to the mountain range, and to the trench.
