Convergent Boundary Colliding Plates Subduction zones form when a continental plate is colliding with an oceanic plate. Subduction zones also form when two oceanic plates collide. The continental crust is lighter because of the quartz and feldspar minerals in granite.hen the two plates meet the oceanic crustal plate always subducts beneath the continental plate. The subducting oceanic plate bends and plunges beneath the lighter continental plate until it melts. When two oceanic plates meet and form a subduction zone the heavier and denser of two oceanic plates subducts.

An example of a convergent boundary is? In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of the lithosphere move toward one another and collide.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. This depends on the nature of the plates involved.

- 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.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.

- Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced down into the mantle. Regions where this process occurs are known as subduction zones. Rates of subduction are typically in centimetres per year, with the average rate of convergence being approximately two to eight centimetres per year along most plate boundaries.

What is a subduction zone and what types of plate boundaries have subduction zones? One plate may be more dense than the other, and with the two plates pushing against each other, the plate that is more dense will slide under the other plate. The plate sliding under is said to subduct the other plate, and this creates what is called a subduction zone. Not all convergent plate boundaries have subduction zones, but all subduction zones are formed at convergent plate boundaries.

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.

Plate Boundaries Also known as passive plate boundaries. 1  The main effects of a conservative plate boundary are earthquakes, which can be fairly violent and frequent. 2  Two plates slide past each other, without creating or destroying any land. Although often not as violent as those on destructive plate boundaries, volcanoes and earthquakes do occur on constructive plate boundaries. 2  They also cause mid-ocean ridges to form. 3  Two plates move away from each other.

- 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.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.

Principles of Plate Tectonics (Part 2) The collision of the plates causes subduction and destruction of the ocean plate. Note the formation of a trench at the plate boundary and a line of volcanoes called an island arc. (Diagram by Phyllis Newbill). In the diagram above, the ocean lithosphere subducts underneath the continental lithosphere.This results in the destruction of the ocean lithosphere and the formation of magmas (with island arc volcanoes above). The deep ocean trench marks the plate boundary and is where the subduction of the ocean lithosphere begins.t these boundaries, two neighboring plates move away from each other. Continental rift valleys are characterized by normal faulting and basalt-rich volcanoes. The diagram shows a typical continental rift. Note the central rift valley that includes volcanoes.

- The three types of dynamic plate boundaries are the convergent, divergent, and the transform boundaries. The Juan de Fuca microplate system consists of a subduction zone along the North American plate at both the Gorda and the Juan de Fuca plates.The system meets the Pacific plate along a divergent zone at the east most boundaries.This divergent zone is composed of three major sea mount ridges (the Gorda, Juan de Fuca, and the Explorer ridges) which feed both the Juan de Fuca microplates to the west and the Pacific plate to the east.he three types of dynamic plate boundaries are the convergent, divergent, and the transform boundaries.

Earthquakes: tectonic plates Converging plate boundaries are of two types: 1  Subduction boundaries occur where oceanic lithosphere is pushed beneath continental or oceanic lithospheres. 2  Where two plates converge at an oceanic trench a subduction boundary is formed as cold oceanic lithospheres are pushed back down into the mantle.

Describe the three types of tectonic plate boundaries and motion that occurs at each type of boundaries? The San Andreas Fault in California is one example. 2. Divergent boundaries occur where two plates slide apart from each other. Mid-ocean ridges (e.g., Mid-Atlantic Ridge) and active zones of rifting (such as Africa's Great Rift Valley) are both examples of divergent boundaries.. Convergent boundaries (or active margins) occur where two plates slide towards each other commonly forming either a subduction zone (if one plate moves underneath the other) or a continental collision (if the two plates contain continental crust). Deep marine trenches are typically associated with subduction zones.

- 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. Earthquakes and composite volcanoes are common at this type of boundary. Plates move past on another at transform boundaries. The most famous example of this type of boundary is the San Andreas Fault in California.

Convergent Boundaries Convergent Boundaries. Introduction. Convergent boundaries form when two crustal plates are colliding. The plates form a subduction zone with one plate descending beneath the other plate. One of the converging plates must be an oceanic plate to form a subduction zone. When two continental plates collide mountain ranges like the Himalayas form. Trenches form at subduction zones, USGS. Subduction zone. The subducting plate is being recycled as it begins to melt at about 100 kilometers. The water soaked oceanic plate forms molten rock that collects in magma chambers.

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. The third type of plate boundary occurs where tectonic plates slide horizontally past each other. This is known as a transform plate boundary. As the plates rub against each other, huge stresses are set up that can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.

- Most present day subduction zones extend from trenches on the ocean floor, from where a zone of earthquake hypocentres (called a Benioff zone) extends, at an angle ranging from near-horizontal to near-vertical, to a depth of up to 700 km. Andesitic volcanoes form approximately 100 km above the subducting slab, and the presence of andesitic volcanoes in the geologic record is regarded as evidence of an ancient subduction zone and thus of a destructive plate margin.

What type of plate boundary would cause mountain formation? When transcurrent plate motion occurs between two plates with a component of compression (called transpression) mountains are formed (such as the Coast Ranges of California). Therefore, the answer is, all types of plate boundaries can cause mountain formation.
