This creates features like volcanoes, mountains, and more. The Continental margins consume about 28% of the area of the ocean. Examples in the World Another example of the oceanic-continental convergent boudaries is the Washington-Oregon coastline of the US. What additional items could we add to make this model more realistic? We have a new and improved read on this topic. Try refreshing the page, or contact customer support. Which type of plate boundary did the clay mimic? The Cocos Plate is a small, oceanic tectonic plate named for the Cocos Island and is subducting under Mexico and Central America. Tell us The Indian subcontinent is slowly being destroyed as the mountains grow higher. What is the example of convergent plate boundary? To answer the question What Is A Convergent Boundary?, we first need to understand the meaning of tectonic plates. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. The Himalayas are the biggest and tallest mountains in the world, and they formed from the collision between two continental plates -- the Eurasian Plate and the Indian Plate. This model is very simple and misses the other layers, such as the mantle inside the Earth. 1. For example, watch . Seafloor Spreading Theory Overview & Diagram | Who Discovered Seafloor Spreading? The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. Visit the Interactive Plate Boundary Map to explore satellite images of the Himalaya Range where the Indian and Eurasian plates are currently in collision. When two continental plates collide due to a convergent boundary both plates are buckled upwards. Our goal is to make science relevant and fun for everyone. 55) _____ A) an oceanic-oceanic divergent B) an oceanic-continental convergent C) a continental transform D) a continental-continental convergent E) a continental-continental divergent The lithosphere of the Earth that includes the crust and the uppermost mantle is not continuous in nature but is subdivided into several pieces called tectonic plates. The Pacific Ring of Fire is an example of a convergent plate boundary. Now that we know what tectonic plates mean, we can easily answer the question of what a convergent boundary is. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid. Convergent Plate Boundary Development Subduction about 250 million years ago Pangaea began to break up about 250 million years ago. The North Andean Plate is a continental plate that is located in the northern portion of South America in Ecuador, Colombia, and Venezuela. B) plants probably were tolerant of both tropical and polar conditions. We and our partners use cookies to Store and/or access information on a device. Deep oceanic trenches are produced in the process and the subduction activity might lead to earthquakes or volcanic eruptions. Plate Boundaries and Features Google Form. Rising at the border of Tibet and Nepal, Mount Everest formed from a tectonic smashup between the Indian and Eurasian tectonic plates tens of millions of years ago. An example of such a boundary has been found between the Pacific and the Philippine oceanic plates that led to the formation of the Japanese islands. , under the other (Figure 4.6.1). Oceanic trenches are steep, V-shaped depressions in the ocean. He has a Masters in Education, and a Bachelors in Physics. There are three main types of convergent boundaries because there are two types of tectonic plates: continental and oceanic. However, different types of plates will produce different results in real life, such as island arcs or volcanoes. Magma chambers are produced as a result of this melting, and the magma is lower in density than the surrounding rock material. The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. First it is complex and second, it is poorly understood when compared to the other types of plate boundaries. We also use third-party cookies that help us analyze and understand how you use this website. Along a convergent boundary two lithospheric plates collide against each other. As the oceanic plate gets pushed into the mantle, it reaches high-temperature areas. C) Paleomagnetic reversals. As a result of this, dramatic seismic events can follow like earthquakes, volcanic eruptions, or deformation of the crust. Some well-known examples of this type of convergent plate boundary on our planet include: The Cascades (Western North America) The Andes: (Western South America) Oceanic-Oceanic Convergent Boundary Figure 2.4.4. At what type of plate boundary are the highest peaks on Earth located? It has a length of about 40,000 kilometers. Get unlimited access to over 88,000 lessons. Boundaries are the types of connections between tectonic plates. Often it is the older and colder plate that is denser and subducts beneath the younger and warmer plate. Analytical cookies are used to understand how visitors interact with the website. When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. . The land between the plates is forced upwards to form fold mountains, eg The Alps and Himalayas. So, it is pushed down or subducted beneath the other plate which is warmer and younger. 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. What is the difference between c-chart and u-chart? All other trademarks and copyrights are the property of their respective owners. These volcanoes can lead to the formation of islands. To the west, the Alps grew in similar fashion via the collision of the African and Eurasian plates. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. The process of folding at such convergent boundaries is explained below under the sub-heading: What Type Of Mountain Ranges Form At Convergent Plate Boundaries? Convergent boundaries are highly unstable areas of the lithosphere of the Earth. This can result in one plate sinking under the other, or the two plates colliding to push the lithosphere upwards. These mountains are the highest above sea level on Earth. in Wildlife Ecology and a graduate certificate in G.I.S. Even though this boundary involves the same type of lithosphere, one of the plates will still subduct beneath the other. When two oceanic plates converge, one is pushed under . The buoyant magma chambers begin a slow ascent through the overlying materials, melting and fracturing their way upwards. There is usually a deep ocean trench off the coast of the continent. 2. At a convergent boundary, plates collide and as such are sometimes called "destructive" boundaries because they . This page will be removed in future. (b) Ol Doinyo Lengai volcano and the East African Rift Valley in Tanzania Convergent Boundaries. Continue with Recommended Cookies. The Karakoram Range is part of the Himalayas. This results in the creation of magma chambers at the subduction zones which might ultimately lead to volcanic eruptions and the formation of volcanic island chains in the ocean. 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. The LibreTexts libraries arePowered by NICE CXone Expertand are supported by the Department of Education Open Textbook Pilot Project, the UC Davis Office of the Provost, the UC Davis Library, the California State University Affordable Learning Solutions Program, and Merlot. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. Plate tectonics is driven by convection cells in the mantle. For example, depths of about 160 m can cause the material to reach melting temperatures. I feel like its a lifeline. This is a high activity area that can also literally get too hot to touch! collision theory, theory used to predict the rates of chemical reactions, particularly for gases. Two locations are marked within the rift valley of East Africa . The visualization shows how earthquakes at this margin occur at depth, and define the slope of the subducting plate. Create your account, 26 chapters | Convergent boundaries are just one of three types of tectonic plate boundaries that can form. When one of the plates is an oceanic plate, it gets embedded in the softer asthenosphere of the continental plate, and as a result, trenches are formed at the zone of subduction. . This boundary is a continent-continent convergent boundary. The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today. This deformation can extend hundreds of miles into the plate interior. What is an example of a convergent plate boundary? But the crust is too thick for magma to get through. As a member, you'll also get unlimited access to over 88,000 The Himalayan range is a classic example of fold mountains formed in this manner. Prentice Hall EARTH SCIENCE Tarbuck Lutgens Chapter 9 Plate Tectonics 9.1 Continental Drift An Idea Before Its Time Wegener's. Expert Help. 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. Answer: C. 5) The ________ is an example of a modern convergent boundary where two continents meet. 3) _____. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Home Teaching Plate Tectonics Convergent Boundaries. They formed from the collision of the Nazca and South America plates. Both regions are vulnerable to severe earthquakes associated with this intense plate collision. Mountain ranges can also form as well as earthquake action. Collision Zones and Mountains Instead a collision between two continental plates crunches and folds the rock at the boundary lifting it up and leading to the formation of mountains and mountain ranges. Create your account. Along a convergent boundary two lithospheric plates collide against each other. Hes written for a variety of outlets, including Earth Touch News, RootsRated, Backpacker, Terrain.org, and Atlas Obscura, and is presently working on a field guide. I am currently continuing at SunAgri as an R&D engineer. However, you may visit "Cookie Settings" to provide a controlled consent. Examples in the World One more example is the Cascade Mountain Ranges. 2 : an encounter between particles (such as atoms or molecules) resulting in exchange or transformation of energy. Imagine the world is like an egg, with a shell that is cracked all over. Its a ring covering 15 countries which include New Zealand, Papa New Guinea, Indonesia, Philippines, United States, Japan, Chile, Canada, Russia, Guatemala, and Peru. Facts about Convergent Boundaries 10: a continental-continental plate boundary. Convergent boundaries are the borders between the plates that are moving towards each other and colliding.
