Exactly what happens during subduction depends on the type of tectonic plates involved. { bidder: 'openx', params: { unit: '539971080', delDomain: 'idm-d.openx.net' }},
Convergent boundaries are the boundaries between “two or more tectonic plates” which are coming towards each other. The collision of this oceanic and continental plate was how the Andes Mountains were formed.

There are two types of plates: oceanic and continental.
The Himalayas and the Tibetan Plateau, the result of 50 million years of collision between the Indian and Eurasian plates, are the most spectacular manifestation of this type of boundary.
A convergent boundary, or destructive boundary, is where two plates are moving towards each other and colliding. },{ A convergent boundary is a deforming region where two tectonic plates or fragments move toward each other and collide.

{ bidder: 'pubmatic', params: { publisherId: '158679', adSlot: 'cdo_btmslot' }}]}]; The Himalayas in Nepal, the European Alps and the Southern Alps in New Zealand are all examples of continental-continental convergent boundaries. The crust that makes up continental plates is thicker yet less dense than oceanic crust because of the lighter rocks and minerals that compose it. 25 chapters | pbjsCfg = { The Caribbean and South Sandwich island arcs are found in the Atlantic, while the Indonesian archipelago is a collection of volcanic arcs in the Indian Ocean. The collision of this oceanic and continental plate was how the Andes Mountains were formed.

Working Scholars® Bringing Tuition-Free College to the Community, One plate subducts, forming trenches and volcanoes, Material from subduction zone pushes up, forming mountains, Oceanic plate subducts beneath the continental plate, forming mountains on the continental side and a trench on the oceanic side, Specify the cause of a convergent boundary, Discuss the results of two oceanic plates colliding, Name some examples of convergent boundaries. This, combined with a lack of water laden oceanic crust and sediments, means that little to no magma makes it to the surface and therefore little to no volcanic activity occurs at these types of convergent boundaries.

Continental plates are the part that lies above sea level, but again, the real definition is that the crust is made of granite and other felsic rocks. { bidder: 'ix', params: { siteId: '195451', size: [300, 250] }}, iasLog("criterion : cdo_pt = ex"); { bidder: 'appnexus', params: { placementId: '11653860' }},
A number of features and examples of convergent boundaries will be introduced. { bidder: 'openx', params: { unit: '539971065', delDomain: 'idm-d.openx.net' }},
Convergent boundaries create foreland basins through tectonic compression of oceanic and continental crust during lithospheric flexure.
You can help! Convergent boundaries can also form islands. See all questions in Plate Tectonics and Inside Earth. iasLog("criterion : cdo_ptl = entryex-mcp"); Since both plates are made of basalt, magma generated at these types of convergent boundaries is almost purely basaltic. Convergent boundaries are formed wherever two plates move toward each other.
{ bidder: 'sovrn', params: { tagid: '446381' }}, One example of a subduction zone is the Pacific coast South America.
When one oceanic and one continental plate collide, the denser oceanic plate subducts beneath the continental plate. There are three examples of convergent plate boundaries that occur as the result of continental and oceanic plate convergence: Advertisement Continental vs. Oceanic Convergence When a continental plate and oceanic plate collide, the more buoyant continental plate slides atop the oceanic plate, creating a subduction zone that features deep ocean trenches and volcanic mountains. Examples of how to use “convergent boundary” in a sentence from the Cambridge Dictionary Labs There are three examples of convergent plate boundaries that occur as the result of continental and oceanic plate convergence:
Because the Earth’s tectonic plates fit together like a puzzle, as shown in the map below, this pushing apart motion and creation of new crust at divergent plate boundaries forces plates to collide and be destroyed or subducted at convergent plate boundaries. The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate. googletag.pubads().setTargeting('cdo_alc_pr', pl_p.split(",")); Get access risk-free for 30 days, The Cascade Mountains of western North America and the Andes of western South America feature such active volcanoes. Earth's surface is made up of two types of lithospheric plates: continental and oceanic. When oceanic and continental plates collide, the oceanic plate undergoes subduction and volcanic arcs arise on land. googletag.pubads().enableSingleRequest();
Oceanic plates are made mostly of basalt and other mafic rocks, whereas continental plates are made of granite and other felsic rocks. { bidder: 'onemobile', params: { dcn: '8a969411017171829a5c82bb4deb000b', pos: 'cdo_btmslot_300x250' }},
{ bidder: 'pubmatic', params: { publisherId: '158679', adSlot: 'cdo_btmslot' }}]}]; Oceanic crust is usually ~7-10 km thick, relatively dense (~2.9 g/cm^3), and mafic or basaltic in composition while continental crust ranges from ~25-70 km in thickness and can be composed of several types of rocks from igneous to sedimentary to metamorphic. name: "idl_env",
