Nazca Plate creates deadly earthquakes small oceanic plate. The Andes have about 50 volcanoes. Practice. These differences are vital to our understanding of what events take place when these different types of crust interact as the tectonic plates move. Which south American continental margin is passive and not a plate boundary? It is the solid rock layer upon which we live. The Cascade Mountain Range is a line of volcanoes above the melting oceanic plate. It is either continental or oceanic. The Nazca plate is presently being subducted beneath the South American plate almost at right angles, with a convergence velocity of-8.5 cm yr 4 [e.g., De Mets et al., 1990]. The Washington-Oregon coastline of the United States is an example of this type of convergent plate boundary. At the convergent boundaries the continental plates are pushed upward and gain thickness. These zones, located along mid-ocean ridges, represent areas where upwelling magma creates new oceanic crust. Which diagram shows oceanic-continental convergence? Indian and Eurasian continental plates. It is created here because of the subduction zone created underneath the continental … The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year. In turn, the overriding South American Plate is being lifted up, creating the towering Andes mountains, the backbone of the continent. •oceanic plates=(1)pacific plate (2)Nazca plate (3)west and south american plates (2)continental crust=is solid and the plates are alwaysmoving •continental plates= (1)african plate (2)Southamerican plate (3)Eurasian plate (4)North american plate (5)indo-australian plate Constructive plate boundaries Oceanic/Continental: The Andes. The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into... There are two main types of tectonic plates: oceanic and continental. The Nazca Plate. Nazca Plate. The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. What features are likely found here? Geology. continental plate keeps moving forward into the oceanic plate it continues to be buckled upwards into a fold mountain. Which statement best describes the relative motions of the Pacific and Nazca plates? Answer: A. continental-oceanic convergent. https://www.answers.com/Q/Is_the_Nazca_Plate_oceanic_or_continental The collision or convergence of the continental South American plate and the oceanic Nazca Plate gave rise to an orogeny or a mountain building activity that produced the Andes Mountains. This diverging plate motion creates some of the youngest oceanic crust on the planet. Convergent boundaries or subduction zones occur when two plates collide forcing one of the plates into the mantle underneath the other. One example of this type of oceanic-continental convergent boundary is the Andes mountain range of western South America. Added 220 days ago|5/28/2021 11:54:25 PM Volcanoes, Earthquakes, and Ocean Trenches. The Nazca plate is an oceanic tectonic plate in the southeastern Pacific Ocean that shares both convergent and divergent boundaries, corners multiple triple junctions, contains three seamount chains, overrides four hotspots, and is responsible for the creation of the Andean orogeny (Figure 1). The rocks and geological layers are much older on continental plates than in the oceanic plates. The trench is also a part of the Chile Triple Junction, an unusual junction that consists of a mid-oceanic ridge and the Chile Rise being subducted under the South American plate at the Peru … Write your name next to the figure and upload it. D. Plate X will become crust above the Nazca Plate. Sediment that has accumulated on the continental slope is thrust up into an accretionary wedge, and compression leads to thrusting within the continental plate (Figure 10.4.7). A continental plate is exemplified by the North American Plate, which includes North America as well as the oceanic crust between it and a portion of the Mid-Atlantic Ridge. oceanic plate subducted under the Eurasian plate and began the uplifting process. Here is a picture showing the major tectonic plates of the world. Continents and Oceans Tectonic plates are around 62 miles thick. The latter is an enormous submarine mountain chain that extends down the axis of … Assign Practice. Answer (1 of 9): The earth’s crust is divided up into sections called tectonic plates. ; Continental-oceanic convergent is a type of convergent boundary which is formed if one plate which has an oceanic crust on the top movers toward another plate which has a continental crust on the top. Geology. The Andes have about 50 volcanoes. A tectonic plate (also called lithospheric plate) is a massive, irregularly-shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Is South American Plate oceanic or continental? Is the South American plate a continental plate? Gravity. Continental crust is considerably thicker than oceanic crust with thickness usually ranging between 25 to 70 km as opposed to oceanic crust thickness between 7 and 10 km. A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. Which plate is being subducted beneath western South America? What happens when convergent oceanic and continental plates collide? (2.7 grams per cubic centimetre). About 170 million years ago, the eastern edge of the Nazca Plate was subducted under the western edge of the South American plate. The net movement of the Nazca Plate is to the East. This magma cools over millions of years, producing intrusive igneous rock and new continental crust. What type of plate boundary occurs between the Nazca Plate and the South American Plate? In a subduction zone, some of the molten material—the former seafloor—can rise through volcanoes located near the trench.Jul 13, 2015. ... 30 seconds . The three-dimensional density model that reproduces the gravity field is a In fact, the largest Which diagram shows a plate boundary like the one involved in the formation of these mountains? The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. During the caledonian folding 450 million years ago, the Continental American plate collided with Because of the motion of the plates they can collide, pull apart, or scrap against each other. The current continental and oceanic plates include: the Eurasian plate, Australian-Indian plate, Philippine plate, Pacific plate, Juan de Fuca plate, Nazca plate, Cocos plate, North American plate, Caribbean plate, South American plate, African plate, Arabian plate, the … Not surprisingly, complex movements of three tectonic plates at the CTJ result in numerous earthquakes. As oceanic plates subduct, they melt to form magma. The trench is a result of a convergent plate boundary, where the eastern edge of the oceanic Nazca Plate is being subducted beneath the continental South American Plate. about 20 million years old about 4.0 billion years old about 200 million years old about 570 million years old. Click on the picture to see a larger view. Plate Y is an oceanic plate when it converge with a continental plate X which of the following will most likely to happen? Finally, we observe a negative arrival approximately 55 to 60 km below and subparallel to the subducted oceanic Moho that we relate to the subducting plate's Lithosphere-Asthenosphere Boundary (LAB). continental margin and adjacent Nazca plate sediments shows that the surface sediments can be resolved into three factors (oceanic, continental A, and continental B; see Table 1) using Q-mode factor analysis. ... Table of Contents At a divergent boundary, two oceanic plates pull apart from each other through a process called sea-floor spreading. Lecture #28: Plate Tectonics . 18. Which plate is thicker continental or oceanic? Tectonic Plates. Covers ocean-ocean and ocean-continent convergent plate boundaries, including the creation of volcanic arcs and earthquakes. The Nazca plate subducts under the South American plate. It also produced the largest earthquake ever recorded by seismographs in 1960. The current continental and oceanic plates include: the Eurasian plate, Australian-Indian plate, Philippine plate, Pacific plate, Juan de Fuca plate, Nazca plate, Cocos plate, North American plate, Caribbean plate, South American plate, African plate, Arabian plate, the Antarctic plate, and the Scotia plate. Label the following: Nazca plate, South American plate, oceanic crust, oceanic lithosphere, continental crust, continental lithosphere, and asthenosphere. Here the Nazca Plate is subducting beneath the South American plate. The correlated changes in the plate coupling, fluid content, hydrofracturing, low-velocity layers, and subducted high oceanic features (e.g., Nazca Ridge) beneath the overriding continental plate are expected to jointly influence the along-strike variations in the slab segmentation and seismotectonic properties of the subducted megathrusts. Where the Nazca plate is forced to dip downwards underneath the South American plate a large v-shaped trench is formed which runs parallel to the destructive argin. Log in for more information. A. At about 43,600,000 km 2 in size, it’s the smallest major plate on Earth. The denser oceanic plate (Nazca) moves under the continental plate (South American Plate). African Plate, Antarctic Plate, Eurasian Plate, Australian Plate, Nazca Plate, North American Plate, Pacific Plate and South American Plate. Oceanic crust is denser, can be subducted and is constantly being destroyed and replaced at plate boundaries. The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate. mid-oceanic ridge being subducted under a continental tectonic plate. Where the oceanic plate is forced below the. Two seamount ridges within the Nazca Plate enter the subduction zone along this trench: the Nazca Ridge and the Juan Fernández Ridge. 19. Convergent. The eastern portion of the Nazca Plate is also being subducted along the Peru-Chile Trench, and the Andes mountains are one consequence of this process. Preview. Earth Sciences questions and answers. and 2). Oceanic-Continental Convergence An excellent example of oceanic-continental convergence occurs on the west coast of South America. Which plate subducts when an oceanic and continental plate collide and why? The Andes are a continental arc (narrow, continental volcanic chain) formed due to the volcanism above the subduction zone. continental plate … The magma rises and erupts, creating volcanoes. D 5. MEMORY METER. Oceanic/Continental: The Andes Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction. the Pacific plate the South American plate the Nazca plate the South Atlantic plate. The lack of deep upper-plate seismicity suggests that the Andean crust has remained warm during flat subduction and is deforming ductilely around the subducted ridge. Plates move horizontally over the asthenosphere as rigid units. Here the Nazca Plate is subducting beneath the South American plate. Destructive Margins: Oceanic/Continental. East. Passive margins occur where continental crust and oceanic crust have coupled together and move as one plate. Off the coast of South America, along the Peru-Chile trench, the oceanic Nazca Plate is pushing into and is being subducted under the continental part of the South American Plate. The Antarctic Plate includes continental crust making up Antarctica and its continental shelf, along with oceanic crust beneath the seas surrounding Antarctica. Part of the Plate X will turn into magma. The Andes Mountain Range of western South America is another example of a convergent boundary between an oceanic and continental plate. A mid-ocean ridge separates the Pacific plate and the Nazca plate off the western coast of South America. As the Nazca plate collides with South America plate, the Ande mountains form with the height of 6900 metres in South America. The Andes are a mountain range of volcanos and of course, mountains. Is South American Plate oceanic or continental? Where such rises are being consumed e.g. The collision or convergence of the continental South American plate and the oceanic Nazca Plate gave rise to an orogeny or a mountain building activity that produced the Andes Mountains. When the oceanic plate slides under the continental plate it can also make a trench. B. Nazca oceanic plate and the South American continental plate. When the oceanic plate slides under the continental plate it can also make a trench. Mid-Atlantic Ridge), continental-continental (e.g. Progress. When an oceanic plate converges with a continental plate, the oceanic crust will always subduct under the continental crust; this is because oceanic crust is naturally denser. Subduction zones can happen with oceanic-continental crust or continental-continental crust.
