Convergent plate boundaries are locations wright here lithospheric plates are moving towards one an additional. The plate collisions that happen in these areas have the right to develop earthquakes, volcanic activity, and also crustal dedevelopment.

Convergent Plate Boundary - Oceanic and Continental Plates


*

When continental and also oceanic plates collide, the thinner and also even more dense oceanic plate is overridden by the thicker and also much less thick continental plate. The oceanic plate is compelled dvery own into the mantle in a process known as "subduction." As the oceanic plate descends, it is forced right into greater temperature atmospheres. At a depth of about 100 miles (160 km), materials in the subducting plate start to method their melting temperatures and a process of partial melting starts.


This partial melting produces magma chambers above the subducting oceanic plate. These magma chambers are much less thick than the neighboring mantle materials and also are buoyant. The buoyant magma chambers start a sluggish ascent with the overlying products, melting and also fracturing their method upwards. The size and also depth of these magma chambers deserve to be determined by mapping the earthquake task approximately them. If a magma chamber rises to the surface without solidifying, the magma will break via in the create of a volcanic eruption.

The Washington-Oregon coast of the USA is an example of this form of convergent plate boundary. Here the Juan de Fuca oceanic plate is subducting beneath the westward-relocating North Amerihave the right to continental plate. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate. The Andes Mountain Range of western South America is one more instance of a convergent boundary between an oceanic and continental plate. Here the Nazca Plate is subducting beneath the South Amerihave the right to plate.

Visit the Interenergetic Plate Boundary Map to discover satellite imeras of convergent boundaries between oceanic and also continental plates. Two places are marked to show this type of plate boundary - the Cascade volcanoes along the Washington-Oregon coast of The United States and Canada and the Andes mountain variety on the western margin of South America.

Effects of a convergent boundary between an oceanic and also continental plate include: a zone of earthquake activity that is shpermit along the continent margin but deepens beneath the continent; sometimes an ocean trench instantly off shore of the continent; a line of volcanic eruptions a few hundred miles inland from the shoreline; devastation of oceanic lithosphere.

Convergent Plate Boundary - Oceanic

When a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will certainly subduct because of its greater density. The subducting plate is heated as it is required deeper into the mantle, and at a depth of around 100 miles (150 km) the plate begins to melt. Magma chambers are developed as an outcome of this melting, and the magma is reduced in thickness than the neighboring rock product. It begins ascfinishing by melting and also fracturing its means through the overlying rock product. Magma chambers that reach the surconfront break with to develop a volcanic eruption cone. In the at an early stage stages of this kind of boundary, the cones will be deep beneath the ocean surface yet later on prosper to be better than sea level. This produces an island chain. With ongoing development the islands prosper bigger, merge, and an elongate landmass is developed.


Japan, the Aleutian Islands, and the Eastern Caribbean islands of Martinique, St. Lucia, and also St. Vincent and the Grenadines are examples of islands formed via this form of plate boundary. Visit the Interenergetic Plate Boundary Map to discover satellite imperiods of these 3 locations.

Effects that are uncovered at this form of plate boundary include: a zone of significantly deeper earthquakes; an oceanic trench; a chain of volcanic islands; the destruction of oceanic lithospbelow.

Convergent Plate Boundary - Continental

This is a complicated boundary to draw. First it is facility and second, it is poorly construed once compared to the other types of plate boundaries. In this form of convergent boundary, an effective collision occurs. The two thick continental plates collide, and both of them have a thickness that is a lot reduced than the mantle, which stays clear of subduction (tright here might be a tiny amount of subduction, or the heavier lithospright here below the continental crust can break totally free from the crust and subduct).

Fragments of crust or continent margin sediments can be recorded in the collision zone in between the continents, developing a highly dedeveloped melange of rock. The intense compression have the right to likewise cause extensive folding and faulting of rocks within the two colliding plates. This dedevelopment deserve to extfinish hundreds of miles into the plate inner.

The Himalaya Mountain Range is the best active example of this kind of plate boundary. Visit the Interactive Plate Boundary Map to discover satellite imperiods of the Himalaya Range wbelow the Indian and also Eurasian plates are presently in collision. The Appalachian Mountain Range is an old instance of this collision form and is also noted on the map.

Effects discovered at a convergent boundary between continental plates include: intense folding and faulting; a wide folded hill range; shenable earthquake activity; shortening and also thickening of the plates within the collision zone.
