Two locations are marked to show this type of plate boundary - the Cascade volcanoes along the Washington-Oregon coast of North America and the Andes mountain range on the western margin of South America. Some or all of these activities happen at the convergent boundaries: subduction of the denser plate underneath the less dense one, melting of parts of the subducted plates, plate collision, faulting and folding, crustal deformation, magma generation, volcanic eruptions, and earthquakes. Continental Margin - Explanation, Types and FAQs - VEDANTU Harmony High School. 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. This convergent boundary has a trench and mantle wedge and frequently, a volcanic arc. Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.

The Karakoram Range is part of the Himalayas. To answer the question What Is A Convergent Boundary?, we first need to understand the meaning of tectonic plates. Here again a subduction zone occurs, as does a volcanic arc that develops on the continental side of the boundary; in between, sediments sloughed up against the continental margin form an accretionary wedge. These magma chambers are less dense than the surrounding mantle materials and are buoyant. When two plates of continental crust collide, the material pushes upward. What is an example of convergent boundaries? Continental lithosphere is low in density and very thick. The geological features that are formed at convergent plate boundaries include volcanoes, volcanic arcs, mountains (especially in arcs), oceanic trenches, and island arcs. To unlock this lesson you must be a Study.com Member. Along a convergent boundary two lithospheric plates collide against each other. Japan, the Aleutian Islands, and the Eastern Caribbean islands of Martinique, St. Lucia, and St. Vincent and the Grenadines are examples of islands formed through this type of plate boundary. Both regions are vulnerable to severe earthquakes associated with this intense plate collision. What is the shape of C Indologenes bacteria? After collision the oceanic lithosphere breaks off and sinks into the mantle. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. These scraped-off sediments are what now form the Himalayan mountain range. What do you see at a continent-continent convergent plate boundary? The western coast of South America is a very good example of an oceanic to continental convergent boundary where the Nazca plate is colliding (and being subducted beneath) the South. Plate Boundaries and Features Google Form. An example of this is found at the boundary between the South American continental plate and the Nazca oceanic plate. It is composed of several layers, not including the overlying sediment. Pacific Ring of Fire This is the most famous boundary because it's the most active seismic area in the world.
