Recall that the oceanic crust is predominated by mafic lithology whereas the continental crust is predominated by felsic lithology. ... and subduction zones are its most important tectonic feature. The massive Himalaya mountain chain was created this way, when India slammed into Asia. The process of subduction has created most of the Earth's continental crust. ; The Mariana trench is not the part of the … mid-ocean ranges . convergent. Extrusive landforms are created by igneous activity at the surface of the earth. If the subduction angle is steep then the distance between the arc and the trench will be short.If the suduction angle is shallow the distance is longer. subduction. extreme temperature. Tags: Topics: Question 6 . Rising magma somewhere inside the borders of a plate can create a local "hot spot." The following features and processes have been associated with subduction erosion: Extensional tectonics: ... Subduction erosion do not explain the Miocene transgression further inland in Patagonia. subduction. The denser, subducting plate begins to heat up under extreme pressure near the mantle and melts to create causes melting in the volcanoes. Harry Hess. Which of the following mountain ranges was created by continental suture? Compared with oceanic subduction zones, where altered mafic igneous rocks contain abundant water prior to subduction, descending crust in continental subduction zones was often considered to be drier than the oceanic crust. The descent of oceanic lithosphere into the mantle is the process of _____? Other articles where Subduction volcano is discussed: volcano: Subduction volcanoes: As an oceanic plate is subducted beneath a continental plate, seafloor sediments rich in water and carbon dioxide are carried beneath the overriding plate. canyons. At the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created. 120 seconds . 2 Evidence for Slip on the Hikurangi Subduction Interface Following the Kaikōura Earthquake . rift valleys. Volcanic activity can occur in areas that are in the interior of a plate, far away from spreading centers or subduction zones. Subduction is the driving force behind plate tectonics, and without it, plate tectonics could not occur. A. Acretionary prism: B. deep sea trenches . On the diagram, label the volcanic mountains and the deep ocean trench that geologists could use to identify this plate boundary. Oceanic Trenches. Use the following link to find these answer Magma generation in subduction zones When the (typically very old) oceanic crust sinks back into the mantle in a subduction zone, it comes progressively under greater pressure and temperature. a) continental crust b) ocean trenches c) convergent plate boundary d) subduction zone e) divergent plate boundary d Beneath Earth's surface, where does the heat exchange occur that moves tectonic plates? 24fawsodan 24fawsodan 11/18/2020 Geography College Which of the following features was not created by subduction? Subduction consumes lithosphere and since the surface of the earth is a constant, it compensates for the amount of lithosphere created at divergent plate boundaries.

The process by which the oceanic crust is pulled under the continental crust is called subduction and the zone at which this occurs at the plate boundaries is called the subduction zone. Q. 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. Although the process is not clearly understood,… The inner core of Earth is solid because of the . At a subduction zone the oceanic plate slides under the continental plate. These compounds may act as fluxes, reducing the melting temperature of magma. Rift valley: C. Continental rupture: D. Transform faults: 8. This is because seafloor spreading – the process by which new oceanic crust is created – occurs mostly in the Pacific. Which of the following features was not created by subduction? SURVEY . Q. 1 Answer. A. Hawaiian Islands: B. 45 seconds . An island arc results when one oceanic plate moves under another oceanic plate. This process called subduction, occurs along oceanic trenches called subduction zones where lots of intense earthquakes and volcanic eruptions can occur. The water, thick with dissolved minerals, rises into the upper plate. The Mariana Trench or Marianas Trench, the deepest trench, is located in the western Pacific Ocean.
