The pressure and friction is great enough at these boundaries that the material in the Earth's mantle can melt, and both earthquakes and volcanoes happen nearby. North American Tectonic Plates | Facts, Movement & Locations. Although the Earth feels stationary, in actuality the lithosphere is always moving, and eventually, that movement can create large geological changes. So, it is pushed down or subducted beneath the other plate which is warmer and younger. When two continental plates collide, large mountain ranges form. What is the difference between c-chart and u-chart? Oceanic trenches are steep, V-shaped depressions in the ocean. The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. 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. What is the example of convergent plate boundary? 4.6 Convergent Plate Boundaries - Introduction to Oceanography Continental lithosphere is low in density and very thick. It features sedimentary rocks which is evidence that it originally emerged from the sea. The Indian subcontinent is slowly being destroyed as the mountains grow higher. Oceanic-Continental Convergent Boundary Fig. The sunken plate gets heated in the mantle causing it to melt. Oceanic plates are made of basaltic rocks, which are much more dense. When two tectonic plates move towards each other the boundary is called convergent. At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. 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 magma thus ascends through the crack between the two plates, melting and fracturing the plates as it moves upwards. The North Andean Plate is a continental plate that is located in the northern portion of South America in Ecuador, Colombia, and Venezuela. The formation of the Himalayan and Tibetan Plateau is a result of a continental-continental plate boundary. Plate tectonics is driven by convection cells in the mantle. The continents of Africa, South America, Australia and Antarctica were originally part of a large supercontinent called Gondwanaland. I would definitely recommend Study.com to my colleagues. Convergent Plate Boundaries - Convergent Boundary - Geology There are two types of plates: oceanic and continental. Oceanography Chapter 2 Flashcards | Quizlet These mountain ranges are located in South America. He holds a B.S. At a continental-continental boundary, both plates are of equal density and so they push the lithosphere upward. Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary oceanic or continental . Convergent boundaries are highly unstable areas of the lithosphere of the Earth. 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. She is also certified in secondary special education, biology, and physics in Massachusetts. Along the Pacific Northwest coast, for example, oceanic plates subducting beneath the North American Plate create the Cascadia Subduction Zone, fueling the Cascade Range volcanoes; the Nazca (and, to a lesser extent, Antarctic) plate subducting under the South American Plate, meanwhile, uplifted the Andes and peppered that towering range with volcanoes. Where different oceanic plates run into each other, the older and therefore cooler and denser one dives beneath the other; in other words, it subducts. This is just like what happens if you put your hands on two sides of a sheet of paper and bring your hands together. 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. The amazing Himalaya Mountains are the result of this type of convergent plate boundary. 2.4 Convergent Boundaries - Dynamic Planet: Exploring Geological Continental lithosphere cannot subduct. The Himalaya Mountain Range is the best active example of this type of plate boundary. He has a Masters in Education, and a Bachelors in Physics. A line of volcanoes, known as the Aleutian Islands, is the result of ocean-ocean convergence. An example of this type of convergent boundary is the Washington-Oregon coastline of the US. Divergent Boundary: Definition & Examples, What is a Transform Boundary? flashcard sets. Ocean trenches can also form as well as volcanic eruptions. Continental crust is too buoyant to subduct. Tectonic Plate Boundaries. Oceanic plates are exactly as they sound - the plates below the oceans. Convergent Boundary. Another example of a transform boundary on land is the Alpine Fault of New Zealand. What is convergent boundary? - TeachersCollegesj 5.17: Continent-Continent Convergent Plate Boundaries At a convergent boundary between oceanic and continental lithosphere, the oceanic plate will always subduct, which will cause earthquakes and form volcanic arcs. Contributor: Hobart KingPublisher, Geology.com. The two thick continental plates collide, and both of them have a density that is much lower than the mantle, which prevents subduction (there may be a small amount of subduction, or the heavier lithosphere below the continental crust might break free from the crust and subduct). The tectonic plates of the lithosphere are not static in nature but are constantly moving towards and away from each other. Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. from the University of Wisconsin-Madison. As one plate bends and subducts under the other, it melts into the asthenosphere, and a deep trench forms. Follow the instructions below and then answer the analysis questions to evaluate your work. There are two kinds of plates: oceanic plates and continental plates. 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. Analytical cookies are used to understand how visitors interact with the website. Oceanic-oceanic convergent: a collision between two plates composed of oceanic lithosphere. What processes happen at convergent continental zones? Oceanic Plate Crust Density, Tectonics & Boundaries | What is a Continental Plate? The amazing Himalaya Mountains are an example of this type of convergent plate boundary. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another. This can result in one plate sinking under the other, or the two plates colliding to push the lithosphere upwards. Convergent boundaries can also form islands. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Here are 5 convergent boundary examples in real life. continental. Answer - 1. 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. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. When two such plates approach each other, the older and hence the denser plate usually subducts beneath the other. 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. 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. Its boundaries border other plates such s the Philippine, North American, Nazca, Indian-Australian, Cocos, Juan de Fuca, and Pacific plates. Convergent boundaries can also form islands. At an ocean-ocean convergent boundary, one of the plates (oceanic crust and lithospheric mantle) is pushed, or. PHESCh09.pptx - Prentice Hall EARTH SCIENCE Tarbuck Lutgens Plate boundaries and Plate movements | UPSC - IAS - Digitally Learn Where is the continental crust thickest on Earth. There are also other types of boundaries, including divergent, where plates move apart. Found a content error? Match the tectonic boundary with its direction of motion: Transform Boundary. 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.
