Convergent plate boundaries are places where lithospheric bowl are relocating towards one another. The plate collisions that take place in these locations can create earthquakes, volcano activity, and crustal deformation.

Convergent Plate boundary - Oceanic and also Continental Plates


*

When continental and also oceanic key collide, the diluent and much more dense oceanic key is overridden by the thicker and also less dense continental plate. The oceanic key is forced down right into the mantle in a procedure known as "subduction." as the oceanic plate descends, that is compelled into greater temperature environments. At a depth of around 100 mile (160 km), materials in the subducting plate begin to method their melting temperatures and also a process of partial melt begins.


This partial melt produces magma chambers over the subducting oceanic plate. This magma chambers space less thick than the neighboring mantle materials and also are buoyant. The buoyant magma chambers start a slow climb through the overlying materials, melting and also fracturing their way upwards. The size and depth of this magma chambers can be figured out by mapping the earthquake activity around them. If a magma chamber rises to the surface without solidifying, the magma will certainly break v in the kind of a volcano eruption.

The Washington-Oregon coastline of the United says is an example of this form of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting in ~ the westward-moving phibìc American continent plate. The Cascade Mountain selection is a line of volcanoes over the melt oceanic plate. The Andes Mountain variety of western south America is an additional example of a convergent boundary between an oceanic and also continental plate. Right here the Nazca key is subducting beneath the southern American plate.

Visit the interactive Plate border Map to discover satellite photos of convergent boundaries between oceanic and continental plates. Two locations are significant to present this form of plate border - the Cascade volcanoes along the Washington-Oregon coastline of phibìc America and also the Andes mountain range on the western margin of southern America.

Effects the a convergent boundary in between an oceanic and also continental key include: a zone the earthquake activity that is shallow follow me the continent margin however deepens beneath the continent; periodically an ocean trench automatically off shore of the continent; a heat of volcanic eruptions a few hundred mile inland from the shoreline; damage of oceanic lithosphere.

When a convergent boundary occurs in between two oceanic plates, one of those plates will certainly subduct beneath the other. Typically the larger plate will certainly subduct since of its greater density. The subducting bowl is heated together it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate starts to melt. Magma chambers are developed as a result of this melting, and also the magma is reduced in thickness than the neighboring rock material. It begins ascending by melting and fracturing its means through the overlying rock material. Magma chambers the reach the surface break with to kind a volcanic eruption cone. In the at an early stage stages that this type of boundary, the cones will be deep beneath the s surface yet later prosper to be higher than sea level. This to produce an island chain. With continued breakthrough the islands flourish larger, merge, and an elongate landmass is created.


Japan, the Aleutian Islands, and the east Caribbean archipelago of Martinique, St. Lucia, and St. Vincent and the Grenadines are examples of islands developed through this form of plate boundary. Visit the interaction Plate border Map to check out satellite pictures of these 3 areas.

Effects that are found at this type of plate border include: a ar of significantly deeper earthquakes; an oceanic trench; a chain of volcano islands; the damage of oceanic lithosphere.

This is a daunting boundary come draw. Very first it is complicated and second, that is poorly construed when compared to the other types of plate boundaries. In this type of convergent boundary, a an effective collision occurs. The two thick continent plates collide, and both of them have actually a thickness that is much lower than the mantle, which avoids subduction (there may be a tiny amount that subduction, or the more heavier lithosphere listed below the continental crust could break free from the crust and subduct).

Fragments of late or continent margin sediments could be captured in the collision zone between the continents, developing a very deformed melange that rock. The extreme compression can also cause extensive folding and faulting of rocks within the 2 colliding plates. This deformation can extend hundreds of miles right into the bowl interior.

The Himalaya Mountain selection is the best energetic example that this kind of bowl boundary. Visit the interactive Plate boundary Map to check out satellite images of the Himalaya selection where the Indian and Eurasian key are right now in collision. The Appalachian Mountain variety is an ancient example of this collision form and is also marked on the map.

Effects discovered at a convergent boundary between continental key include: intense folding and faulting; a large folded hill range; shallow earthquake activity; shortening and thickening of the plates in ~ the collision zone.
