- Where 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.hey are associated with different types of surface phenomena. The different types of plate boundaries are: 1  Transform boundaries (Conservative) occur where two lithospheric plates slide, or perhaps more accurately, grind past each other along transform faults, where plates are neither created nor destroyed.

- The lines where they meet are called plate boundaries. There are three main types of plate boundary: divergent, convergent and transform. Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges.Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction.ectonic plate interactions are of three different basic types: 1  Divergent boundaries are areas where plates move away from each other, forming either mid-oceanic ridges or rift valleys. 2  These are also known as constructive boundaries. 3  Convergent boundaries are areas where plates move toward each other and collide.

Unique landforms are created at plates margins. Unique landforms are created at plates margins. There are four types of landforms created at plate margins: fold mountains, ocean trenches, composite volcanoes and shield volcanoes. Fold mountains are created at two types of plate boundary.1  At destructive boundaries: where an oceanic and a continental plate moving together.2  At collision boundaries: where two continental plates moving togther.hield volcanoes are found at constructive plate boundaries. As the two plates move apart magma rises up from the mantle. It then rises up through a vent forming a volcano. 1  Shield volcanoes have a wide base and gently sloping sides.

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.

- 1 A single plate may be part oceanic and part continental. 2  In that case, the boundary between ocean crust and continental crust is not a plate boundary. 3  The mobile part of the mantle under the lithosphere is called the asthenosphere. An oceanic trench forms offshore, and a chain of volcanic mountains forms just inland of the coast. 2  This type of boundary between oceanic crust and continental crust is called an active continental margin since it is a plate boundary. 3  At other convergent boundaries, oceanic plate meets other oceanic plate.

- Subduction Zones. Where two tectonic plates converge, if one or both of the plates is oceanic lithosphere, a subduction zone will form. An oceanic plate will sink back into the mantle.Remember, oceanic plates are formed from mantle material at midocean ridges.here is a deep ocean trench where the oceanic plate bends downward. Volcanic Arcs: The basaltic ocean crust contains hydrous minerals like amphiboles, some of which formed by hydrothermal alteration as seawater seeped through hot, fractured, young ocean crust at the midocean ridge.

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.

Types of Plate Boundaries One edge of ocean crust is subducted beneath the other at an ocean trench. The ocean trench curves outward toward the subducting plate over the subduction zone. Data from earthquakes along the subducting plate show that the angle of subduction increases with depth.

Plate tectonics 1 Divergent boundaries (Constructive) occur where two plates slide apart from each other. 2  At zones of ocean-to-ocean rifting, divergent boundaries form by seafloor spreading, allowing for the formation of new ocean basin.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.

Tectonic Plates and Plate Boundaries The most active divergent plate boundaries are between oceanic plates and are often called mid-oceanic ridges. 3. Transform boundaries – where plates slide passed each other. The relative motion of the plates is horizontal. They can occur underwater or on land, and crust is neither destroyed nor created.

Earthquakes: tectonic plates Convergent boundary zones are characterized by deep-ocean trenches, shallow to deep earthquakes, and mountain ranges containing active volcanoes. Image: Convergent plates collide into each other In general, where an oceanic and a continental plate collide, the denser oceanic plate will be forced under (subduction) the other.

Oceanic trench Oceanic trench. Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. Oceanic trenches are topographic depressions of the sea floor, relatively narrow in width, but but very long. These oceanographic features are 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.

- 1 The boundary between two plates can be a divergent boundary, a convergent boundary or a transform boundary. 2  The lithosphere is composed of the crust, and some of the upper mantle. 3  Mature oceanic plate is approximately 80-100 km thick, of which, the upper 5-7 km is oceanic crust. At other convergent boundaries, oceanic plate meets other oceanic plate. 2  This results in an oceanic trench and a chain of volcanic islands known as an island arc. Japan, the Philippines and the Aleutians are examples of island arcs. 3  At some convergent boundaries, two continents collide.

Tectonic Plates and Plate Boundaries There are three main types of plate boundaries: 1. Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. The denser plate is subducted underneath the less dense plate. The plate being forced under is eventually melted and destroyed. i. Where oceanic crust meets ocean crust Island arcs and oceanic trenches occur when both of the plates are made of oceanic crust.

Divergent boundaries Plate tectonics two oceanic plates, an oceanic and continental plate, or between provides the mechanism to recycle the Earth’s crust. Destruction (recycling) of crust takes place along convergent Divergent Margins boundaries where plates are moving toward each other, and sometimes one plate sinks (is subducted) beneath another. The location where the sinking of a plate occurs is called a subduction zone. A transform boundary is where plates slide past each other with no creation or destruction of lithosphere. Plate Margin Examples There are three general types of plate boundaries: divergent, convergent, and transform.

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. When two plates are moving away from each other, we call this a divergent plate boundary. 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. While the process is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.

Subduction Zones Subduction zones are convergent boundaries where at least one of the tectonic plates is an oceanic crust. The new oceanic crust that forms in spreading centers is recycled in these zones. Subducting oceanic plate. The oceanic crust melts as it descends into the lithosphere and upper mantle. Subducting plates ring the Pacific Ocean creating volcanic arcs and megathrust earthquakes. Coastal area where an ocean plate is subducting beneath a continental plate.
