Now that we know what tectonic plates mean, we can easily answer the question of what a convergent boundary is. Fold mountains are created where two or more of Earths tectonic plates are pushed together. Northern Cascade Mountains in the Pacific Northwest America, Specify the cause of a convergent boundary, Discuss the results of two oceanic plates colliding, Name some examples of convergent boundaries. 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). e.g., a lithospheric mantle and an oceanic crust. Convergent boundary types include oceanic/oceanic, oceanic/continental and continental/continental. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. C) northwestern movement of Baja California and a sliver of western California. 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. For example, depths of about 160 m can cause the material to reach melting temperatures. Convergent boundaries occur where tectonic plates collide, which takes place where two oceanic plates meet, where two continental plates meet or where an oceanic plate meets a continental plate. The asthenosphere is a layer (zone) of Earths mantle lying beneath the lithosphere. This cookie is set by GDPR Cookie Consent plugin.

Examples in the World One more example is the Cascade Mountain Ranges. They create many of the mountain ranges, volcanos, and even earthquakes that occur on Earth. Continental vs. Continental Boundary When two continents converge, neither is subducted because the continental rocks are relatively light and, like two colliding icebergs, resist downward motion. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. To answer the question What Is A Convergent Boundary?, we first need to understand the meaning of tectonic plates. The Himalayan Mountains are an example of: a. continent-continent convergent boundary b. divergent boundary c. transform boundary d. rift movement along divergent boundary Mount St. Helens, Mount Rainier, and other active volcanoes along the Cascade Ranges are examples of: a. ocean-ocean convergent boundaries What is formed at continental continental plate boundaries? K2, pictured here, is over 20,000 feet high. You are likely to get some from a convergent boundary. In convergence there are subtypes namely: If one plate was less dense, it would sink beneath the other, forming volcanoes or island arcs. . They are formed from the subduction of oceanic plates. Thus, the following convergent boundaries occur when two plates meet: When two plates meet, one inevitably gives way and sinks below the other. Arrange the tectonic plates end to end to create a boundary. This is because in any chemical reaction, chemical bonds in the reactants are broken, and new bonds in the products are formed.

The other two zones being the deep-ocean basins and mid-ocean ridges. The ranges lie in a subduction zone making them very unusual since these are high mountains. As the plates of the earth move, three types of tectonic plate boundaries occur. Big mountains! As one plate bends and subducts under the other, it melts into the asthenosphere, and a deep trench forms. . The ocean floor consists of many materials, and it varies by location and depth. At the subduction zone of a convergent boundary, the denser tectonic plate slides underneath the relatively less dense plate. Other Words from collision Synonyms Choose the Right Synonym Example Sentences Learn More About collision. This convergence boundary is the result of two plates colliding. Log in Join. Manage Settings 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. Continental collision is a phenomenon of the plate tectonics of Earth that occurs at convergent boundaries. This is how mountain ranges form, including even the biggest ones in the world, like the Himalayas. North American Tectonic Plates | Facts, Movement & Locations. This cookie is set by GDPR Cookie Consent plugin. The Alps are some of the most majestic mountains around. As the denser plate descends, it might enter depths where the higher temperature environment cause the materials making it up to partially melt. Oceanic-oceanic convergent: a collision between two plates composed of oceanic lithosphere. collision theory, theory used to predict the rates of chemical reactions, particularly for gases. 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. What is the difference between c-chart and u-chart? They formed from the African and Eurasian tectonic plates colliding together. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary. However, different types of plates will produce different results in real life, such as island arcs or volcanoes. This makes it descend or get subducted under the Caribbean Plate. Litho is from the Greek word lithos, meaning stone. SCIENCE 0373C0. 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. At an ocean-ocean convergent boundary, one of the plates (oceanic crust and lithospheric mantle) is pushed, or. Students should see that the clay collided together, forming a mountain range similar to that which occurs when two continental plates collide. Also, 90% of all earthquakes take place here. To better organize out content, we have unpublished this concept. The Pacific Ring of Fire is an example of a convergent plate boundary. Boundaries are the types of connections between tectonic plates. Convergent boundaries are of 3 types. The Juan de Fuca oceanic plate is subducting beneath the westward moving North American Continental plate. Answer - 1. In a subduction zone, the plates colliding can push the less dense plate upwards, forming mountains. What is the result of this? 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. At what type of plate boundary are the highest peaks on Earth located? 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. Create your account. Examples of how to use "convergent boundary" in a sentence from the Cambridge Dictionary Labs Oceanic plates are made of basaltic rocks, which are much more dense. The Caribbean region includes the Caribbean, Nazca, North Andean, Panama Plates, and the Cocos and Galapagos microplates. These cookies track visitors across websites and collect information to provide customized ads. convergent boundary The collision between two plates that are moving towards each other is called a convergent boundary. They formed from the collision of the Nazca and South America plates. Start by rolling out two flat sections of clay, each of a different color. Here the oceanic plate of Juan de Fuca is subducting beneath the North American continental plate that is moving in a westward direction. Other features of an oceanic/oceanic convergent boundary are the forearc basin between the trench and the island arc and the backarc basin on the opposite side of the arc. Divergent Boundary: Definition & Examples, What is a Transform Boundary? It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid. A convergent boundary, or destructive boundary, is where two plates are moving towards each other and colliding. Which type of plate boundary did the clay mimic? A) plants were distributed to current locations by ancient glacial ice sheets. Social boundaries are types of rules that are considered common because most of the . Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Since the African plate was denser, it was subducted under leaving the lighter continental crust above it. At continental-oceanic or oceanic-oceanic boundaries, the plates are different densities, and one sinks under the other. When two oceanic plates meet, they form large trenches underwater. Subduction Zones & Processes | What is Subduction? What do the C cells of the thyroid secrete? Continent-Continent Convergent Plate Boundaries Loading. As a member, you'll also get unlimited access to over 88,000 Examples of accreted terranes are found in southeast Alaska and northern Washington state. Convergent continental-continental boundary. (5) $2.00. 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. Copy. Continental-continental convergent boundary: describes the collision of two tectonic plates composed of continental lithosphere. 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. Instead, the crust tends to buckle and be pushed upwards or sideways, creating mountains. Convergent boundaries can also form islands. They form as two continents collide. 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. Get unlimited access to over 88,000 lessons. A convergent boundary marks the area where two tectonic plates collide or meet each other. | 22 A semi-solid, such as marshmallows, slime or putty, could be used as that material and the plates could be something more solid, such as cardboard or paper, to represent the crust. These mountains are the highest above sea level on Earth. 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 Fragments of crust or continent margin sediments might be caught in the collision zone between the continents, forming a highly deformed melange of rock. The types are ocean-ocean, ocean-continent, and continent-continent. The amazing Himalaya Mountains are an example of this type of convergent plate boundary.

Click, SCI.ESC.269 (Continent-Continent Convergent Plate Boundaries - Earth Science). The cracks in the egg are boundaries between plates. She has a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. 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. Often it is the older and colder plate that is denser and subducts beneath the younger and warmer plate. Convergent boundaries are very common around the world. C) Paleomagnetic reversals. 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. Its like a teacher waved a magic wand and did the work for me. This creates features like volcanoes, mountains, and more. The sunken plate gets heated in the mantle causing it to melt. 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. Since the South American plate is much colder than the Caribbean plate, it is denser. Explain how a bacterium and a human being satisfy the postulates of the cell theory Kabuuang mga Sagot: 1. magpatuloy. A) westward movement of South America over the (subducting) Nazca plate. So, it is pushed down or subducted beneath the other plate which is warmer and younger. Visit the Interactive Plate Boundary Map to explore satellite images of these three areas. These are going to be your tectonic plates. Oceanic plates are denser due to being made from basalt rock and thus will sink, or subduct, under continental plates, which are made of granitic rocks. 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. . With continued development the islands grow larger, merge, and an elongate landmass is created. 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. Another type of convergent plate boundary is when two continental plates collide. Use the resource below to answer the questions that follow. During the 165 million years of dinosaur existence this supercontinent slowly broke apart. The geological features that are formed at convergent plate boundaries include volcanoes, volcanic arcs, mountains (especially in arcs), oceanic trenches, and island arcs. The World Ocean is the name for the collective group of oceans on the planet. This was an ocean-continent boundary in which the oceanic plate was subducted under the continental plate. Plate tectonics is driven by convection cells in the mantle. The material has nowhere to go but up (Figure below)! copyright 2003-2023 Study.com. This typically happens at oceanic-continental boundaries and oceanic-oceanic boundaries.
