- The process by which the oceanic crust is pulled under the continental crust is called subduction and the zone at which this occurs at the plate boundaries is called the subduction zone. At the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created.These can be many of thousands of kilometres long and 8 to 10 kilometres deep making them the deepest part of the ocean floor.t the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created.

What happens when an oceanic plate and continental plate collide? Report Abuse. The collision of an oceanic plate, and a continental plate produce a plate boundary known as a subduction zone. The colder, denser [typically basaltic crust (approx. 3.3g/cm^3)] oceanic plate is forced underneath the less dense [typically granitic (d= 2.7)] continental crust.

- 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.s a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries. When two plates move towards one another, they form either a subduction zone or a continental collision.

Oceanic/Continental: The Andes The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. This is marked on the ocean surface by the presence of the Peru-Chile (or Atacama) Trench.

Chapter 2 - Plate Tectonics Identify each type of convergent plate boundary. Since oceanic plates are denser than the continental plates, they will subduct to great depths when they converge with continental plates. When two oceanic plates converge, the denser of the two will subduct; whereas when two continental plates converge, neither will subduct. Therefore, the resulting geologic feature depends on the types of plates that converge. Depending on the type of plate convergence, different features could result.

Oceanic trench Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor.Oceanic trenches are a distinctive morphological feature of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few mm to over ten cm per year.he greatest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level.

Two locations are marked: 1) the Mid-Atlantic Ridge exposed above sea level on the island of Iceland, and 2) the Mid-Atlantic Ridge between North America and Africa.

- Stable subduction zones involve the oceanic lithosphere of one plate sliding beneath the continental lithosphere or oceanic lithosphere of another plate due to the higher density of the oceanic lithosphere. That is, the subducted lithosphere is always oceanic while the over-riding lithosphere may or may not be oceanic.

- An active continental margin refers to the submerged edge of a continent overriding an oceanic lithosphere at a convergent plate boundary by opposition with a passive continental margin which is the remaining scar at the edge of a continent following continental break-up.

- The Tonga Trench is a convergent plate boundary. The trench lies at the northern end of the Kermadec-Tonga Subduction Zone, an active subduction zone where the Pacific Plate is being subducted below the Tonga Plate and the Indo-Australian Plate.uch oceanic trenches are important sites for the formation of what will become continental crust and for recycling of material back into the mantle. Along the Tonga Trench mantle-derived melts are transferred to the island arc systems, and abyssal oceanic sediments and fragments of oceanic crust are collected.

- At convergent boundaries, tectonic plates collide with each other. The events that occur at these boundaries are linked to the types of plates — oceanic or continental — that are interacting. Subduction Zones and Volcanoes. At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust.

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.onvergent Boundaries between Tectonic Plates. Convergent boundaries where tectonic plates move toward each other generally result in the subduction of one plate into the mantle, consuming part of the lithosphere.

When an oceanic plate converges with a continental plate, it is always the ocean plate that subducts beneath the continental plate. Continental lithosphere lies at a higher surface elevation than oceanic lithosphere because of its lower overall density.

seafloor spreading An active plate margin is an actual plate boundary, where oceanic crust and continental crust crash into each other. Active plate margins are often the site of earthquakes and volcanoes. Oceanic crust created by seafloor spreading in the East Pacific Rise, for instance, may become part of the Ring of Fire, the horseshoe-shaped pattern of volcanoes and earthquake zones around the Pacific ocean basin.

- 2 types of Continental Margins: Active continental margin and Passive continental margin •Active Continental Margin –occur along plate boundaries (where plates are actively moving) –This is where mountain building takes place!! –Ex.) Nazca Plate (oceanic crust) subducting beneath South American Plate (causing mountains to form, earthquake and volcanic activity. (Andes Mountains) •Passive Continental Margin –do not occur along plate boundaries –These are stable margins and accumulate large amounts

- Active continental margins, i.e., when an oceanic plate subducts beneath a continent, represent about two-thirds of the modern convergent margins. Their cumulated length has been estimated to 45,000 km (Lallemand et al.,
