The subduction zone eventually becomes inactive The two continents become welded together as they are compressed together over time. Answers: 1 Show answers Another question on Chemistry. Visit the Interactive Plate Boundary Map to explore satellite images of divergent boundaries between continental plates. This is where an oceanic and a continental plate collide. The Appalachian Mountains resulted from ancient convergence when Pangaea came together. Deep oceanic trenches are produced in the process and the subduction activity might lead to earthquakes or volcanic eruptions. An analogy for tectonic plates is the pieces of a puzzle. The tectonic plates of the lithosphere are not static in nature but are constantly moving towards and away from each other. I am currently continuing at SunAgri as an R&D engineer. 1 : an act or instance of colliding : clash. Examples of ocean-continent convergent boundaries are Subduction of the Nazca Plate under South America which has created the Andes Mountains and the Peru Trench Subduction of the Juan de Fuca Plate under North America created the Cascade Range. His primary interests from both a fieldwork and writing perspective include landscape ecology, geomorphology, the classification of ecosystems, biogeography, wildlife/habitat relationships, and historical ecology. ( now the highest in the world) The geographic location of the point of collision . (b) Ol Doinyo Lengai volcano and the East African Rift Valley in Tanzania Convergent Boundaries. The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. 2.4.3. The consent submitted will only be used for data processing originating from this website. What is the example of divergent boundary? Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. Fold mountains are created through a process called orogeny. At convergent boundaries that involve two continental plates, the plate tectonics is a bit more complex than in the other two types of convergent boundaries. Continental collision is a phenomenon of the plate tectonics of Earth that occurs at convergent boundaries. , under the other (Figure 4.6.1). The characteristics that describe convergent boundaries are subduction, where one plate sinks under another, and collision, where two plates crash together. An error occurred trying to load this video. Convergent boundaries are very common around the world. When continental and oceanic plates collide, the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The Himalyas the highest mountains in the world were once the seafloor. The sunken plate gets heated in the mantle causing it to melt. The western coast of the Americas part of the Pacific Ring of Fire, named for the Pacific basins energetic volcanic and seismic turmoil hosts this type of tectonic convergence. Analytical cookies are used to understand how visitors interact with the website. lessons in math, English, science, history, and more. An interesting feature of the Alps is the Matterhorn which has rock materials from both the Eurasian plate and African plate but in different places. Divergent boundaries are formed where two plates pull apart from each other (the most famous example is the Mid-Atlantic Ridge, where the North American and Eurasian plates diverge). Two plates slide past each other. The Appalachian, Ouachita, and Marathon mountains comprise a collisional mountain range formed 500 to 300 million years ago, whereas the Brooks Range is the result of a more recent continental collision. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt. The size and depth of these magma chambers can be determined by mapping the earthquake activity around them. Since the South American plate is much colder than the Caribbean plate, it is denser. One of them is Mount Everest which is the earths highest mountain. Mountain ranges can also form as well as earthquake action. Are All Supplementary Angles Linear Pairs? Youngest person to climb Mount Everest (2003-2010), Youngest person to climb Mount Everest (2001-2003). The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. Convergent Boundary. In physics, a collision takes place when particles, aggregates of particles, or solid bodies move toward each other and come near enough to interact and exert a mutual influence. There are several landforms and features that can develop at convergent plate boundaries. When this happens, one plate usually subducts beneath the other plate, and in the case of two continental plates, the collision can be so violent that the plates merge together. The Himalayas in Nepal, the European Alps and the Southern Alps in New Zealand are all examples of continental-continental convergent boundaries. Oceanic/Oceanic Oceanic/Continental Show. The magma that escapes during subduction can also form new crust and mountain ranges. In this activity, you're going to be modeling a convergent boundary out of clay. Which type of chromosome region is identified by C-banding technique? A) plants were distributed to current locations by ancient glacial ice sheets. The volcanoes located in the Pacific Ring of Fire and the Mount Etna volcano on the east coast of Sicily were formed in this manner. Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent; sometimes an ocean trench immediately off shore of the continent; a line of volcanic eruptions a few hundred miles inland from the shoreline; destruction of oceanic lithosphere. You are likely to get some from a convergent boundary. Prior to 500 million years ago, the ancient North American continent was separated from Gondwanaland and Eurasia by a large body of water known as the Iapetus Ocean. A) westward movement of South America over the (subducting) Nazca plate. In this satellite image is an erupting volcano, topped by snow or ice, and surrounded by seawater - a member of the Aleutian chain. The Andaman and Nicobar Islands located in the Indian Ocean and part of the territory of India were also formed in a similar manner. flashcard sets. 2011-01-19 04:03:05. North American Tectonic Plates | Facts, Movement & Locations. The collision of the plates has produced the Himalayas Range which has produced 15 of the highest mountains in the world. These are determined by the area or location on the earths crust where the boundaries are formed. A) plants were distributed to current locations by ancient glacial ice sheets. Slide the plates together and observe what happens to the clay. At an ocean-ocean convergent boundary, one of the plates (oceanic crust and lithospheric mantle) is pushed, or. This cookie is set by GDPR Cookie Consent plugin. Students should expect for the clay to collide together, forming a mountain range similar to those that occur when two continental plates collide. Learn the definition of a convergent plate boundary and explore the different types of convergent boundaries, where they occur, and see detailed examples. Both regions are vulnerable to severe earthquakes associated with this intense plate collision. Northward migration of India Note that this figure is a simplification and does not take into account the huge amount of crustal shortening that would have occurred in both the Eurasian and Indian plates. Match the tectonic boundary with its direction of motion: Transform Boundary. SCIENCE. 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. Effects found at a convergent boundary between continental plates include: intense folding and faulting; a broad folded mountain range; shallow earthquake activity; shortening and thickening of the plates within the collision zone. I would definitely recommend Study.com to my colleagues. What are two examples of this type of plate boundary? Answer: C. 5) The ________ is an example of a modern convergent boundary where two continents meet. Continental lithosphere cannot subduct. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. | Transform Boundary Examples & Features. He holds a B.S. Examples of Convergent Boundaries The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate. It has been suggested that the next supercontinent will form in 200-250 million years, so we are currently about halfway through the scattered phase of the current supercontinent cycle. Where oceanic and continental plates collide, the former subducts beneath the latter because ocean crust rich in iron and magnesium is denser than continental rock. As a result of this boundary, intense faulting and folding can occur. When two continental plates converge, they smash together and create mountains. As one plate bends and subducts under the other, it melts into the asthenosphere, and a deep trench forms. The lithosphere includes the Earths crust and the uppermost part of the mantle. Tectonic Plates Overview & Types | Tectonic Plates Definition, Divergent, Convergent, & Transform Plate Boundaries, Evidence for the Mechanism of Continental Drift. The Himalayas (Figure below) are the world's tallest mountains. 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. In fact, the collision continues to this day -- the Himalayas are still growing! Ridge Push Overview & Examples | What is Ridge Push? Like an example of one between China and Vietnam. (Confidently Correct) Reason - Each different reasoning for Where can you find an example of this type of convergent boundary?
