- As 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. 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.

Convergent boundary When 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 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 Convergent boundaries are the place where two tectonic plates converge (i.e. two plates move toward each other). These zones tend to be where compressional stresses are active and this results in thrust or reverse faults being common. Converging plate boundaries are of two types: Subduction boundaries occur where oceanic lithosphere is pushed beneath continental or oceanic lithospheres. Where two plates converge at an oceanic trench a subduction boundary is formed as cold oceanic lithospheres are pushed back down into the mantle.

Earth Science in Maine In convergent/destructive plate boundaries, two plates collide into each other. They may form mountains, mountain ranges, volcanoes and many other landforms. In divergent/constructive plate boundaries, two plates move away from each other. They can form mid-ocean ridges, island arcs and many other landforms. When a small volcano explodes at or in sea the lava cools and forms a hard surface and forms mountains, Plautus.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. Magma from the mantle solidifies into basalt, a dark, dense rock that underlies the ocean floor. 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.

- Divergent plate boundaries usually occur deep in the oceans. The mid-oceanic ridges are an example of this type of volcanic action. Occasionally, as is the case with Iceland, oceanic ridges rise above the surface of the ocean. Convergent Tectonic Plates Contrarily, convergent plate movement causes more visible volcanic action. Famous volcanoes, such as Vesuvius or Mount St. Helens, were caused by converging tectonic plates.

- They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and back into the mantle to melt. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts.The third type is transform boundaries, or a boundary where plates slide past each other, forming strong earthquakes.his happens at a convergent boundary. 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.

- 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. Image: Cutaway artwork showing different types of plate boundary and hotspots.his 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.

What are the different types of plate tectonic boundaries? If one of the colliding plates is topped with oceanic crust, it is forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents. Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed. Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions.

- Metamorphism affecting a large area or regional metamorphism involves large increases of temperature and pressure. Contact metamorphism is common at both convergent and divergent plate boundaries, in areas where molten rock is produced. Regional metamorphism largely occurs at convergent plate boundaries. Each of these types of metamorphism produces typical metamorphic rocks, but they may occur in different sequences. For example, both regional and contact metamorphism produce schists and shales.

What are the different types of plate tectonic boundaries? A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes strike along the rift.Beneath the rift, magma—molten rock—rises from the mantle.agma rises into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents. Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed.

- Volcanism occurs regularly at two of the three types of plate Boundaries. The most volcanism occurs at diverging plate boundary where plates separate. Volcanoes also form at converging plate boundaries where one plate dives beneath the other at subduction zones.olcanos are most commonly found at subduction zone boundaries. This is where the thinner oceanic plates get pulled under the thicker continental plates. As the plates go deeper, they melt and form pockets of magma which can cause mountains to be built and as the hot magma rises, it erupts out of volcanos.

Convergent Boundary Colliding Plates Colliding Plates. Convergent boundary, divergent boundary and transform boundary are the three types of boundaries that form due to plate tectonic movement. Converging plates usually form subduction zones.Subduction zones ring the Pacific Plate causing frequent earthquakes, volcanic eruptions, and tsunamis.ontinental 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.

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. 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. The third type of plate boundary occurs where tectonic plates slide horizontally past each other. This is known as a transform plate boundary.

Types of Geography Features at a Plate Boundary Convergent boundaries, ... Transform boundaries occur where plates are sliding past one another. ... Types of Geography Features at a Plate Boundary;...renches 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.
