It was formed subduction because of the Philippine Plate over the Pacific plate. Where convergent boundaries do may take place? The amazing Himalaya Mountains are the result of this type of convergent plate boundary. The collision of this oceanic and continental plate was how the Andes Mountains were formed. Continent-Continent Convergence, Formation of the Himalayas oceanic crust, the outermost layer of Earths lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries. For example, watch . As a member, you'll also get unlimited access to over 88,000 Ocean-Continent Convergent Plate Boundaries ( Read ) | Earth Science | CK-12 Foundation Ocean-Continent Convergent Plate Boundaries Covers ocean-ocean and ocean-continent convergent plate boundaries, including the creation of volcanic arcs and earthquakes. What would happen if one of the "plates" was less dense than the other? What are the different types of plate tectonic boundaries? But they're defined not so much by the oceans, but by the material they're made of. Slight movements in the lithosphere can cause earthquakes when the plates bump against each other. What additional items could we add to make this model more realistic? Ethan Shaw is an independent naturalist and freelance outdoors/nature writer based in Oregon. All rights reserved. (5) $2.00. Divergent Boundary: Definition & Examples, What is a Transform Boundary? Convergent Boundary. The classic example of a continental/continental convergent boundary is the rumpled overlap where the Indian Plate drives into the Eurasian Plate, a tectonic collision that has thrown up the greatest mountains in the world the Himalayas as well as the vast, high Tibetan Plateau. Visit the Interactive Plate Boundary Map to explore satellite images of these three areas. The simple answer is that not all of the ocean floor is made of sand. Three Types of Convergent Boundaries | Sciencing 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. Two locations are marked within the rift valley of East Africa . When tectonic movements cause two tectonic plates to approach each other at the convergent plate boundary, deposits of sedimentary and metamorphic rocks at such boundaries often crumple and fold to form mountains called fold mountains. I would definitely recommend Study.com to my colleagues. The World Ocean is the name for the collective group of oceans on the planet. C) entire earth had polar conditions at the . Now that we know what tectonic plates mean, we can easily answer the question of what a convergent boundary is. These are going to be your tectonic plates. Answers: 1 Show answers Another question on Chemistry. Describes convergent plate boundaries where two continental plates come together. Continental-continental convergent boundary: describes the collision of two tectonic plates composed of continental lithosphere. Home Teaching Plate Tectonics Convergent Boundaries. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. When two plates come together, it is known as a convergent boundary. They unbound and unloose the imprisoned contents of the earths tombs to give us a magnificent display of geological formations. The others are divergent and transform boundaries that are created in a different way. 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. Advertisement cookies are used to provide visitors with relevant ads and marketing campaigns. Where do convergent boundaries occur? What are the three types of convergent 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. Found a content error? What is the example of divergent boundary? An example of this type of convergent boundary is the Washington-Oregon coastline of the US. Continental vs. Continental - Plate Tectonics PHESCh09.pptx - Prentice Hall EARTH SCIENCE Tarbuck Lutgens The subduction zone is the area where two plates are sandwiched on top of each other, like a tectonic BLT. Where convergent boundaries do may take place? Oceanic trenches are steep, V-shaped depressions in the ocean. The amazing Himalaya Mountains are an example of this type of convergent plate boundary. Oceanic plates are made of basaltic rocks, which are much more dense. For example, depths of about 160 m can cause the material to reach melting temperatures. succeed. Manage Settings Chains of volcanic islands are also formed. Copy. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. What is the ring of fire and where is it located? Continent-Continent Convergent Plate Boundaries - CK-12 Foundation Oceanic Plate Crust Density, Tectonics & Boundaries | What is a Continental Plate? Draw upon what you've learned from this lesson on convergent boundaries when it's time to: To unlock this lesson you must be a Study.com Member. Click, We have moved all content for this concept to. They form as two continents collide. The Continental margins consume about 28% of the area of the ocean. The magma thus ascends through the crack between the two plates, melting and fracturing the plates as it moves upwards. The characteristics that describe convergent boundaries are subduction, where one plate sinks under another, and collision, where two plates crash together. Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022. A) westward movement of South America over the (subducting) Nazca plate. Effects that are found at this type of plate boundary include: a zone of progressively deeper earthquakes; an oceanic trench; a chain of volcanic islands; the destruction of oceanic lithosphere. However, different types of plates will produce different results in real life, such as island arcs or volcanoes. There are three important parts to collision theory, that reacting substances must collide, that they must collide with enough energy and that they must collide with the correct orientation. This indicates how strong in your memory this concept is, Continent-Continent Convergent Plate Boundaries. This creates features like volcanoes, mountains, and more. 4.6: Convergent Plate Boundaries - Geosciences LibreTexts They formed from the collision of the Nazca and South America plates. 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. It does not store any personal data. Continental Margin - Explanation, Types and FAQs - VEDANTU Students should expect for the clay to collide together, forming a mountain range similar to those that occur when two continental plates collide. March 22, 2013. Answers: 3 Get Iba pang mga katanungan: Science. As a result of this boundary, intense faulting and folding can occur. Convergent boundaries can also form islands. She is also certified in secondary special education, biology, and physics in Massachusetts. 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. This is called subduction. The buoyant magma chambers begin a slow ascent through the overlying materials, melting and fracturing their way upwards. Such a convergent boundary includes a seafloor trench marking the earthquake-rattled subduction zone as well as an island arc: a line of volcanoes created by rock-melt in the mantle associated with subduction. The Earths lithosphere, composed of the outer crust and the rigid, uppermost section of the mantle, is divided into mobile segments called tectonic plates on which the oceans and continents ride. 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 formation of the Himalayan and Tibetan Plateau is a result of a continental-continental plate boundary. Since the African plate was denser, it was subducted under leaving the lighter continental crust above it. Exactly what happens during subduction depends on the type of tectonic plates involved. Continental-Continental Convergent Boundaries are possible when two continental plates converge. Continental plates are made of granitic rocks like quartz and feldspar, which makes them less dense. Also, 90% of all earthquakes take place here. Here the Juan de Fuca oceanic plate is subducting beneath the westward-moving North American continental plate.
